I know it may be hard to pay regular price for them when you read about others on this board getting them at the clearance prices. However, my daughter and I both called Brita, and were both told that the sports bottles have definitely been discontinued. Brita will no longer be manufacturing and selling them. Their reasoning was that the market in recent years hasn't justified continuing production. So - if you do find them, go ahead and buy them - along with any filters you can find. Full price is better than no Brita bottles at all. BTW, I have found that the filters last quite a bit longer than the estimate given on the package. We keep using them until the water starts to taste funny again.
