Age of "new" tires

Yes, show me the dates before I pay. I don’t buy from local stores because they charge too much.

This year I bought 3 new sets of tires.
2 new sets off eBay, both 3 months old.
1 set from an online tire seller, I called first they said up to 3 years old is what they sell. They are 1.5 years old.
