Amazon & eCommerce Weekly News Roundup — Week 12
A seller shipped 2,000 units of a seasonal product last week. Referral fee change kicked in three days before delivery. His margin math was off by 2% across the entire shipment. That’s not a rounding error — that’s real money gone before a single customer clicked “buy.” Week 12 brought several moves from Amazon and the broader eCommerce space that sellers need to account for now, not next quarter.
Amazon’s Referral Fee Updates Are Already in Effect — Did You Catch Them?
Amazon adjusted referral fees in multiple categories this year, with some categories seeing reductions and others quietly creeping up. Apparel under $15 now has a different fee structure than it did 18 months ago. If you haven’t re-run your margin calculations on existing listings, you’re flying blind.
We see this weekly at our warehouse — sellers price their products based on numbers from six months ago and then wonder why their net payout looks wrong. The math changes. Check your fee structure in Seller Central against your current price points. Specifically look at the “Revenue Calculator” under “FBA” for each ASIN, not just your category’s published rate.
FBA Inventory Limits Are Getting Tighter Heading Into Q2
Amazon’s restock limits have been quietly adjusting based on IPI scores and sell-through rates. Several sellers we work with got surprised by lower-than-expected limits in March. If your IPI dropped below 400 at any point this quarter, expect constraints to follow.
According to Amazon’s own guidelines, sellers with IPI scores below 400 are subject to inventory storage limits — and those limits can change as frequently as every two weeks during high-demand periods. One of our clients learned this the hard way when 600 units sat at our dock because their FBA limit had been cut and they hadn’t checked Seller Central in 10 days. Now they check it every Monday. You should too.
Shopify’s Q1 Numbers Signal a Shift in DTC Behavior
Shopify reported stronger-than-expected merchant growth heading into Q1. More interesting: fulfillment through Shopify’s own network is gaining traction among mid-size sellers doing $500K–$2M annually. That’s the exact seller profile that often uses Amazon as their primary channel but is starting to hedge.
This matters for FBA sellers because it signals where the market is moving. Sellers who are only Amazon-dependent are increasingly looking at 3PL options to keep inventory staged for multi-channel fulfillment. At 365PrepCenter, we handle prep for both FBA and FBM shipments — same dock, same team, no separate setup fees for clients splitting inventory between channels.
Poly Bag and Suffocation Label Requirements Haven’t Changed — But Violations Are Up
Honestly, this one shouldn’t still be a news item in Week 12 of the year. But here we are.
A missing poly bag costs about $0.04 at volume. Amazon’s unplanned prep fee for it is $0.52 per unit. On a 500-unit shipment, that’s $240 in fees for a $20 problem you could have solved at your prep center. The suffocation warning label must appear on any poly bag with an opening of 5 inches or larger. That’s been the rule for years. We still receive shipments weekly where sellers skipped it.
If you’re prepping your own products, build a checklist that gets signed off before pallets leave your facility. Or send it to a prep center and stop thinking about it.
TikTok Shop’s U.S. Future Remains Uncertain — But Sellers Are Already Reacting
The on-again, off-again status of TikTok in the U.S. is forcing sellers who built significant revenue there to re-evaluate their channel mix. Some are pushing harder into Amazon. Others are testing Meta’s native shopping tools. Either way, it’s creating urgency around having flexible inventory positions.
Sellers who can pivot quickly between channels are the ones winning right now. That means inventory staged in a 3PL — not locked inside an Amazon fulfillment center — gives you actual flexibility. Worth factoring into your Q2 planning.
What to Watch in the Next Two Weeks
Amazon’s Spring Deal event window is on the horizon. Submission deadlines for Lightning Deals typically fall 4–6 weeks before the event. If you’re planning to participate, those windows may already be open or opening shortly. Log into your Deals dashboard and check your eligible ASINs now. Don’t let this one slip through because you were focused on something else.
365PrepCenter is currently receiving Q2 inventory from sellers prepping for deal events and seasonal restocks. Getting product prepped and staged early avoids the last-minute rush that always costs someone a missed deal window.
