Looking to buy some bearings

I’m new to yoyoing and want to buy a couple different types of bearings to see which I like the most, without having to pay retail price if at all possible. I’m interested in these bearings.

Twisted Trifecta
One Drop 10 Ball
Terrapin X Wing (10 Ball preferably)
Dif e Yo Konkave

I’d like to try and get the one drop and at least one of the other three at once. I’m new to this forum and not sure how this usually works, so I guess just pm me or leave a reply if you can help me out.
