About 5 months ago I got the Amazon initial warning email of "hey, we notice a lot of returns. Can we do anything to make your shopping experience better?" I had made 3 returns in the prior 12 months out of about 30 orders. I also had a couple order cancellations...not sure those count. Apparently this is the first warning shot where you can eventually get banned from Amazon. And since they're eating the world, I would find that pretty disruptive in terms of being able to quickly/easily acquire obscure items. Well I recently ordered a ton of guitar parts. I sent back tuners (wrong hole size). Hardware I didn't need. And now a couple nuts I ordered are not tall enough... Eat the $8 or process a return...sigh. Of course places like StewMac would be far better to order from. But that $8 nut would cost $9.99 to ship.
