I have to recommend the seller painit on ebay. His prices are very reasonable and the postage is also good.
I have had a few Mexican Pinguicula (I blame jeff for that ) and the odd Drosera (corky's fault) from him recently and can't fault the plants or the service. I've previously had other plants and the service was the same then.
I received an order of Pinguicula today from CarniSana. The order was placed on the 29th July so it was fulfilled quickly. The plants were well packed in 4 tubs, 2 species to a tub, which were in turn inside a super long tom. I ordered 8 different and received multiple plants of each plus there's always a leaf or 20 to use as cuttings. Check out their site, the prices are very good and so are postal rates.
