Ok so I am doing this in my other auction as well. For every 500 credits I will add an extra tester. So at 500 I will add a new tester and so on. Keep bidding I have lots of testers!
To help you get more bids and possibly more credits for your item, I've changed the category of this listing from Other Stuff to Home & Garden > Decor. This will help bidders find your item, and will prevent it from getting flagged by users. Thanks for your cooperation and good luck!
