Amazon has a million things you can’t find at Walmart.
Sometimes the prices are high, but often they are low with free shipping.
Bought a special USB for my camera, checked local walmart online first.
They said they had it in stock fo $7.
Went down ther, got jerked around for over an hour, wasted gas, no cable, no joy.
Ordered on Amazon for 50C, came with a free Iphone stylus.
With shipping it was less than $5 and was in my mailbox 3 day later.
Works like a hose.
I use it to find retro brand stuff or close copies. Many of the discussion groups offer up valuable feedback on stuff. My true coffee and tea drinking favorite, the Sunshine Golden Raisin Biscuits had been off the market for 20 years. Product feedback forums helped me find almost exact versions. I then discovered there were thousands of people looking for the same “Gone” products which are still made in unknown places under unknown brands.
