There are many stores that sell tassimo t-discs, or as some websites call them, t disks. I have purchased tdiscs from Wal-Mart and Target. The problem with these stores is that they have a very limited variety of t-discs for the Tassimo line of machines. Ordering online gives you a much larger variety to choose from.
Some might think that you can get tassimo t-discs from ebay, but actually, I have found the prices on ebay are actually much higher than the stores and other online shops. Finding cheap t discs or cheap t-discs is as easy as using websites to shop.
Try those links above and I bet you find some great deals on tassimo tdiscs because I have purchased from there before, a trusted Amazon seller is always a plus and most of the time you can get free shipping.
