Returns due to failure for checking part numbers...

[px_455]

Here we go again...

Buyers returning perfectly working products for reason "Doesn't work / defective" when the real problem is someone failed to check the part number... Folks, if I sell a product part number N04 that part will NOT fit the machines requiring part numbers N01, N02, N03 nor N05!!!
I know this is hard to understand but the part that I sell with part number N04 will ONLY fit the machine requiring part number N04.  Checking part numbers is the buyer's responsibility!

People no longer read, modify your title a bit. For example.

N04 ITEM - COMPATIBLE SOLELY WITH N04

tweak the titles a bit, people love to skim through and not read.

Maybe it'll be a good idea to send Buyers a note and remind them of part number prior to shipping, if you have this problem requiring many times!

eBay buyers are well known to have the lowest shopping IQs in the world .

To minimize this problem, you have to describe compatibility in the photos, in the title, in the description, and in the structured data.

I wish eBay had the ability for a seller to have a pop-up window with important sizing / compatibility information before the buyer commits to the purchase ... something like:

Before buying, make sure you are buying the right part.  This is the N05 part designed for the ACME Coyote Rocket, and it is not compatible with either the ACME Darwin Award Rocket or the ACME Flat Earther Rocket.
