Yep! I can sell you all Sanrio Sets. TBT's basically the forum currency that you can get by posting or replying to threads like these. At the moment, you have 1,177 TBT bells with you. You can see how much bells you have by clicking "My Profile" at the upper left-hand side and then clicking "About Me". Scroll down a bit then you'll see the word "Bells" and beside it, the amount you have.
THEN, you can TRANSFER bells by clicking someone else's profile, going to their "About Me" page , and clicking on the number beside bells. After that a screen should pop up asking you how much you'd like to transfer to that person.
ANYWAY, I'll get working on your order right away! Expect a reply within the day.
(I didn't mean for those to rhyme)
