I contacted Mr P. Twice, once where a sweater was reduced while it was shipped to me and I asked if the price could be adjusted. They didn't, fine bc quickly afterwards it had sold out.
The second time I ordered a lilac TF polo which was advertised as 100% cotton, it home it had 15% elasthan. I contacted Mr P who argued that it was the same shirt that I had ordered and I could send it back if I didn't want it. Maybe if they had offered me something I would have kept it, but I am now very likely to send it back.
