Returns decide this channel before advertising ever gets a say. A footwear or technical outerwear catalogue carries a return rate that would be unremarkable on your own store and is ruinous inside a fulfilment network, where every returned unit is a fee, a grading decision and a possible unsellable write-off, and where the platform's own metrics start penalising the listing. So the first piece of work is not a campaign, it is the arithmetic: contribution per unit after referral, fulfilment, storage and a realistic return rate, run per SKU. Some of your styles will carry it comfortably. Some will not, and they should either sit on the channel seller-fulfilled or stay off it entirely.
The second piece is the catalogue structure that reduces the returns in the first place. Size, width and volume as real variation themes rather than forty unlinked listings; last and fit notes in the bullets and A+ modules; comparison to models a buyer is likely to already own; and the same aggregated fit feedback you use on your own product pages carried over into the content the platform lets you control. Every one of those is a return you did not pay for twice. Colour and material attributes matter here too, because the marketplace search engine matches on structured fields, not on the paragraph you wrote about the tannery.
The third piece is who you are up against on your own detail page. Durable goods with strong specialty distribution attract resellers, closeout buyers and grey stock, so Brand Registry, controlled distribution terms and enforcement against genuine infringement all belong at the start rather than after you lose the buy box on your best style. Beyond Amazon, the useful channels here are specific rather than numerous: eBay is legitimately where parts, discontinued sizes and refurbished stock trade, which suits a brand already running a repair or resale programme; Faire is the right route for the specialty retail accounts this metro's brands live on; and TikTok Shop is honestly a weak fit for a considered high-ticket purchase, though it can work for the accessory and consumable end of a catalogue. Coffee sits differently again, because roast date is the product and a fulfilment centre does not care what day it was roasted.
