Besides: The chances of either of them going belly-up are faaaaar lower than for Joe Random's webshop or, heaven forbid, physical store.
A massive issue missing from this statement are the problems around fakes which has grown and is unaddressed by Amazon. Not such an issue with books though.
But still. Shopping at Amazon is so damn riskless, why would I buy at a small shop I don't know anything about? I got burned, family got burned - I just became very, very selective with buying elsewhere.
The risk is too damn high.
WTF, here in Germany (or rather Europe as a whole) it is the other way around for the mandatory 2 years - if something happens, you return the item where you bought it and the seller is completely responsible for dealing with everything, and on the hook for delivering you a working item.
Only after these two years expire and you have an "extended warranty" in place you have to deal with the manufacturer.
