I'm ordering some more plants on Monday :) and the weather forecast changed again so it might be warm enough for no heat pack!
Panda has an FB page with all the plants and invertebrates that are available with prices, too. I'm not sure if its posted here but I tried to get a link:
I'm on my phone so I hope it works. I find the FB page easier to browse than this thread :) I definitely recommend Panda for plants! I haven't ordered shrimp, though.
