We usually purchase them off Amazon but I had a coupon so we thought we'd pick up a pack at Target. The Playtex brand liners are really expensive at Target, even with the coupon they would have been a dollar more than the Amazon price. They do however, sell a generic Up & Up brand of liners (only available in stores). They're pretty cheap so we decided to give them a try.
The Up & Up brand are okay. We're currently giving Harry seven ounces of formula at a time. We use the powdered kind you have to mix and since using the generic liners we've had to switch to six ounces because seven is really hard to mix, even though they can hold up to eight ounces.
Here's a comparison of what the liners look like holding eight ounces of liquid. Up & Up brand on the left, Playtex on the right.
And not to confuse you, here the Playtex is on the left and the Up & Up is on the right.

As you can see, it would be impossible to add formula powder to the Up & Up liners. I would say six ounces is the limit on these; seven is doable, but difficult. The nice thing about the Playtex ones is that they expand to ten ounces to make mixing nice and easy.
So, if you want to save a little money, I say go for the Up & Up liners if your baby is drinking six ounces or less per feeding. They are sturdy, BPA free and fit great in the Playtex bottles. Unfortunately we'll have to switch back to the Playtex ones since Harry is eating so much these days.
