I do agree, but the prevalence of Amazon's practices are very well known. Returned products being put back on a shelf or back into supply will obviously happen, but I have seen it happen almost zero with the retailers I mentioned (We have also been using target.com, costco.com, etc.). It definitely takes some effort and a little more shopping around, but it has mostly been working for us (in my household).
