The fee went up; your margin went down; and the question every seller forum asks within the hour is "do I put my prices up?" The honest answer: run one division, then decide like a shopkeeper rather than a spreadsheet.
Work out the change per typical order in pounds, not percentages. A 0.48% addition on a £28 order is 13p — absorbable almost anywhere. An extended base or a 1.5-point rise on the same order might be £1+ — that's margin you'll miss by December. Under ~1% of your price, absorption is usually right: repricing admin, rounding awkwardness and buyer-visible movement cost more than the fee does. Over that, pass it on deliberately.
To keep your old net, divide the old price by (1 − new effective rate) rather than "adding a bit" — the comparator gives you the effective rate per channel. Then round up to a clean number: £24.50, not £24.37. Clean prices read as decisions; precise ones read as arithmetic, and buyers who sense arithmetic start doing their own.
Never change prices alone and silently on the same listing photos. Fold the rise into your next natural update — new photography, refreshed descriptions, a new colourway — so returning buyers see a listing that improved, not one that just got dearer. And do the whole shop in one sitting rather than dribbling rises across weeks: one visible adjustment reads as a repricing; five read as drift.
A fee rise on one channel is a price cut on all the others. Before passing costs to your buyers, check whether the smarter move is shifting effort — new listings, your best photography, cross-link priority — toward the marketplace that didn't just get more expensive. Sellers with a two-channel setup get to make that choice; single-channel sellers get to absorb it.
