Mine are £1.95 each for tetras and bars, she hasn't put her price up though, and says she's not planning to at the moment.
I'm probably in my CDC's house for about 10 minutes usually, it can vary though. I go in, we have a bit of a chat about how I've found the week and that's what will vary the length of time I'm in there. If I say it was good etc. then it's a bit more in and out, however I know I can talk to her about issues and stuff, and that'll mean I'm there longer. She'll then weigh me, measure me and talk about whether I'm happy on the plan I'm on, and then sort my CD packs for the week. She texts me quite a few times throughout the week too, just checking I'm ok, reminding me to stay strong etc. Like this morning I got a text message saying about the weekend can be hard, but that we can do it and it's worth sticking to it. I know that if I get tempted, I can text her. So while she's maybe not the cheapest CDC, she's not too expensive, and I like her, she's good!
