So I just noticed that Amazon will sell you a 2 year warranty on pretty much anything for a bit under 10% of the product cost. I used this warranty once on a Kindle, and they refunded the money without a hassle.
I think I'm going to try this out on some cheap pedals (ZERAY ZP-108S). It only adds about $3 over Aliexpress and it should ship faster. The warranty claims to cover wear and tear as well as defects, so it could actually be a good deal...
Anyone else used the Amazon warranty on bike parts?
