Well, I own a hybrid shop and each hybrid cost 1 TBT each, or 200k IGB (in game bells), but I can make that cheaper for you, since you're new and need an introduction to the forums. If you don't know what TBT is, it's the in-website currency that you get from writing posts and donations. I believe that 1 line = 1 TBT and so on, but the max TBT you can get from a post is 10 TBT. Here, you can use TBT to buy art, buy in-website collectibles, buy items from ACNL and so on. You could also use in-game bells (IGB) to spend on the forums, but the most preferred currency is TBT. Sorry about the hard explanation.
