My question on duplicate listings is different than the answers given

[accent3407]

My question specifically is, does eBay have an alert system to tell you, already have listed this same item? I have several duplicate items and would be nice if it could warn you before listing a duplicate.

Generally you will get a warning as you list a similar item. It's not foolproof though.

1) If you are "relisting" something you had listed before, it's a really good idea to do a search on seller hub for a keyword

2) You can sort your listings alphabetically on Seller Hub to look for similar titles

3) You can use this free 3rd party tool to check for duplicates
