How many consumers have this style of interaction:<p>* buy an item from Amazon (coffee maker or otherwise)<p>* realize the build quality&#x2F;size is rubbish (which from some of the less well known sellers, it really can be)<p>* return the item using Amazon&#x27;s generous returns policies (never had one rejected, I&#x27;ve used it many times)<p>* buy a different item in the same category.<p>* repeat?<p>If this type of purchase happens a non-negligible number of times, could that be the reason we see so many &#x27;buy more of X!&#x27; style ads?
