I was just going to make a similar positive review for Peter at CottageCrafts, but rather than create a new thread it seems better to revive an old one so that people can read all the reviews. I've purchased a few things from them now, and every time they have been prompt, very friendly, and helpful. The prices are very good, and you can get decent sizes. Most places only seem to stock 50 ml bottles of 30% CaCl2, which is gone pretty quic, but the 200 ml bottle of 50% CaCls that Peter Supplies should last much longer. Anyway, for anyone in NZ, I recommend checking them out. He's willing to send you an invoice so you can make a direct payment rather than credit card over the net if you're at all wary of that.
