Until last week, they carried Delta 8 carts. Those were $26.99 and lasted a week. Weds I go in and they've replaced those with disposable that costs $16 MORE AND YOU ONLY GET 1/3 of the product. I bought this pos weds afternoon. It's friday night and it's gone and I used it no more or less than the two carts I bought before it. TALK ABOUT A RIP OFF
