Bluestone did get my last order wrong. It was the first and only time they've ever sent me something wrong so I was really surprised. I've ordered from them for years without a single problem.
This year I ordered (among other things) two Eryngium Sapphire Blue but one of the tags says it is Eryngium Big Blue. I couldn't tell them apart and I had already planted them. I was concerned because I had wanted Sapphire Blue because it's sterile and my yard is too small to deal with excessive seeding of prickly plants.
I didn't expect Bluestone to do anything since I didn't call right away and I had already ripped the pots off and planted them both. It was my fault for not checking the tags before planting. But they were very nice and offered me a refund or two replacement plants in the fall (since they are currently out of stock). No need to send pix or return the plants. That was really nice of them.
I still hate their coo coo pots but now that I've dealt with their customer service for the first time, I can say that their CS was great.
