Am I the only one that feels uncomfortable returning stuff? Took me years to get to get over, and yet I'd still prefer to forego buying something rather than returning it..
And furthermore now that I'm doing so many returns, I've become completely fine with returning new unopened things that I decide I don't want, effectively delaying the actual purchase decision 30-90 days. Parts that I want to have on hand while doing a project, limited time deals from pricing games, extra copies I order preemptively to quicken the above self-QC song and dance, etc. If I already have to go to a store to drop off returns, my marginal cost of returning additional things is very low.
If returns were really affecting bottom lines, companies could do a lot to tamp down on these dynamics. At this point I suspect it's more profitable for them not to. I think the manufacturing costs of stuff has just gotten so low that the physical items themselves just don't end up mattering compared to the overall margins.
