Purging base insert cards?

[mattyeah]

What is the most efficient and effective way of selling off unwanted base inserts, they're taking up a lot room in my storage boxes and since I only collect base sets I have no use for them.

Any suggestions? sell in lots of 10? cheap mystery packs?

Hehe I collect base sets

I don't mind trading autos/GUs for them?
