If you are looking to sell a killstreak kit that you currently own, you can select it from your backpack when creating a new trade.

If you are looking to search the site for a specific killstreak kit, that feature has yet to be implemented. However one way around that is to put a killstreak kit on the left side of the search section, and type in a weapon name in the phrase search area.

For example, if I wanted to search for a specialized killstreak flamethrower, I'd search for a specialized killstreak kit, and type 'flamethrower' into the phrase search. Which gets me these results: http://www.tf2outpost.com/search/256184953

You won't be banned for trading with users banned for trading with a marked scammer (provided they don't have any pending Steamrep reports or anything else suspicious, such as a private profile). However we highly recommend that you avoid trading with banned users altogether. As it stops potential scammer alts from gaining profit off fraudulent trades.

The level on an item will rarely effect the price of something. It's purely based on whether the buyer is collecting a certain level.
The most common levels collected (from what I've seen) is 1, 42, 69 and 100. Though keep in mind if the item is unique, the level usually won't affect the price.

I just paid $15 primarily for the auto bump feature, and it's not working.

I'd either like my money back, or preferably the feature fixed.

Please don't necrobump.

If you're having problems with premium, create a support ticket on the site.
