The 3 Most Common (and Costly) Mistakes I See with Fillmore Container Orders

Skip the checklist at your own risk. It’s saved us over $2,800 in the last year.

I’m the one who manages packaging procurement for our small-batch food line. Over the past five years, I’ve personally submitted—and messed up—enough Fillmore Container orders to fill a small warehouse with unusable jars and lids. The most expensive single mistake cost us $890 and a week of production delay. Now, I maintain a pre-submission checklist that’s caught 47 potential errors for our team in the last 18 months. If you’re ordering glass containers, bottles, or caps from any bulk supplier, the three most critical checkpoints are container finish, closure compatibility, and shipping specs. Miss any one, and you’re likely looking at a costly reorder.

Why you should (maybe) listen to me

I’m not a packaging engineer. I’m a pitfall documenter. My job, born from painful experience, is to turn our team’s expensive lessons into a simple process so no one repeats them. The template I use is: "[Job title] handling [service type] orders for [years] years. I've personally made (and documented) [number] significant mistakes, totaling roughly $[amount] in wasted budget." For me, that’s "Operations manager handling packaging orders for 5 years. I've documented 12 significant mistakes, totaling roughly $2,800."

My biggest regret? In September 2022, I ordered 500 clear glass Boston round bottles for a new syrup line. I checked the diameter, the height, the material. They arrived perfect… and we couldn’t seal them. I’d missed the finish specification—the threaded part at the top. The caps I had on hand were for a different finish. 500 bottles, useless. That’s a $450 lesson in reading the product details more carefully.

Mistake #1: Assuming "Standard" Means Universal (The Finish Fiasco)

This is the number one error for newcomers. You find a 16 oz amber jar you like, you see it has a "standard" mouth, and you assume the caps from your last supplier will fit. They probably won’t.

"Finish" refers to the threaded neck of the container. A "400 finish" isn’t the same across all glass manufacturers. Fillmore’s 400 finish might have slightly different thread dimensions or tolerance than another supplier’s. In my first year, I made this classic spec error. I’d saved $30 buying caps from a different vendor, thinking a 400 finish was a 400 finish. The result? Caps that were either too loose and leaked, or so tight they cracked the glass during capping. We lost about 50 jars before we stopped the line.

The fix: Never assume compatibility. If you’re switching container suppliers or cap suppliers, order a small sample batch first to test the fit. Fillmore’s product pages clearly list finishes (like 400, 415, 450). Use that exact number, and when in doubt, buy your closures from the same place you buy your containers. The peace of mind is worth the potential few extra cents per unit.

Mistake #2: Focusing Only on Jar Cost, Ignoring Total Closure Cost

Here’s the penny-wise, pound-foolish scenario I see all the time. A team member finds a great price on 8 oz jelly jars. They’re thrilled to save $0.05 per jar over the previous quote. They place the order for 2,000 jars. Then, they go to order the lids. The surprise wasn’t the jar price—it was that the matching plastic lids were twice as expensive as the ones for the slightly more expensive jar. Net loss on the total package: over $150.

I once saved $80 on a bulk jar order by choosing a vendor with a cheaper base price. I ended up spending nearly $400 more on specialized closures that only fit that jar’s unique finish. The "budget" choice wasn’t smart in the end.

The fix: Always do a total unit cost calculation: (Jar Price + Lid Price + Any Seal/Insert Price) ÷ Quantity. Before you finalize any container order, have the specific closure product page open and do the math. Fillmore often has discount codes for bulk orders, which can apply to both jars and lids—factor that in.

Mistake #3: Treating Shipping as an Afterthought

Glass is heavy and fragile. Shipping isn’t a minor line item; it’s a major cost and risk factor. The disaster in Q1 2024 for us was a $3,200 order of 12 oz bottles. We needed them in 10 days for a production run. We chose the standard ground shipping to save money.

The shipment was delayed in transit. Then, when it arrived, three of the five cases had significant breakage because the pallet wasn’t configured ideally for cross-country freight. We missed our deadline, had to source emergency local bottles at a premium, and spent hours filing a freight claim. The "savings" on shipping cost us in time, product, and stress.

The fix: Plan shipping as part of your initial sourcing. For large or heavy orders (like poster board bulk or cases of glass), get a freight quote. Consider:
1. Transit Time: Does "standard" meet your deadline with a buffer?
2. Packaging: For glass, ensure you’re selecting options like "full pallet" or "heavy-duty packaging" if available.
3. Location: Shipping costs can vary wildly. Calculate it early. Sometimes, a supplier with a slightly higher product price but a closer warehouse is cheaper overall.

My Simple Pre-Checkout Checklist

This is the physical list I have taped to my monitor. Nothing gets ordered until I answer YES to each point:

1. Finish & Closure Match: Have I confirmed the exact finish number and purchased (or verified) compatible closures from the same supplier?
2. Total Cost Calculated: Have I calculated the final cost per sealed unit (container + lid + seal)?
3. Ship Date Verified: Does the "ships in" or estimated delivery date (plus 2-3 day buffer) meet my production deadline?
4. Sample Tested (For New Items): For new containers or closures, have I ordered a single case to physically test fill, seal, and label application?

When This Advice Doesn't Apply

I’d argue this checklist is essential for any food, beverage, or cosmetic producer ordering primary packaging. But it’s less critical for purely decorative containers or one-off craft projects where a perfect seal isn’t necessary. Also, if you’re ordering something like employer letterhead or custom envelope stickers, you’re in a different ballgame—your concerns are paper weight, print alignment, and adhesive quality, not thread finishes.

And look, I’m not saying Fillmore Container is the only option. There are great suppliers out there. But their variety and bulk pricing, especially with those coupon codes, work for our needs. My goal isn’t to sell you on them; it’s to make sure that whoever you order from, you get exactly what you need, without the expensive hiccups I’ve had. An informed customer saves everyone time and money.

I still kick myself for some of those early mistakes. But if this list helps you avoid just one of them, then writing it was worth it.
