This happens to me basically everywhere. Recently, $300 of crap from Target soaked in laundry detergent. Usually the amounts are small enough that they say not to return the items - I pay the cleaning price and at least most of the stuff doesn't go to waste. But this time they wanted it all sent back, so have fun with that (and they wouldn't even cross-ship). It still boggles my mind how they're able to waste so much stuff and lose so much money seemingly without care.

The only mitigation I've found is to make multiple orders separating out heavy/bulky/liquid/light/fragile items, shipping cutoffs permitting. But of course this is less likely to work with Amazon where they coalesce different orders. (The latest incident was due to forgetting to do this, which should be their job, for them)
