If you're just buying pallets of random returns, removing one category of items from that random pallet may not even devalue the pallet for that customer either. Heck, it might even make the pallets more valuable to have less variety in them (after all, the stroller-only pallets became more valuable when they are stroller-only).
Cherry picking pallets is a big deal and all the warehouses try to say they don't, but everyone does it. The only one I went to that was legit, had people line up outside when a truck arrived and everyone bid on the pallets as they were coming off the truck. Not surprisingly the value I got out of those pallets was 10-20x more than from other pallet warehouses.
All of the other places are cherry picking and reorganizing pallets to elicit higher bids and tend to run their own parallel retail / resale operations. It's probably necessary though because the guy selling directly off the truck went out of business last year.
