Like all Masdevallia growers here in the UK we sometimes use eBay and I have to agree there are some dodgy sellers on there, However I wouldn’t normally recommend a seller but I’ve found Spicesotic plants to be reasonable in plant quality, postage and cost, you can view them on their website at www.spicesoticplants.co.uk or visit there eBay shop at stores.ebay.co.uk/spicesotic-plants. But this is the only seller I would use and recommend. Good Luck with future purchases.
