Ours has always been like that? It opened about 8 years ago, I think I have bought one thing in there that hasn't ended up being taken back (although to balance that slightly the dress I did keep is one of the most complimented pieces of clothing that I own).
It's one of the only clothes shops in our local town so we don't have much choice! Bought some relatively decent dresses and work wear from there but recently been flabbergasted by the prices!! They seem to have regular 20% off so I think they just hike the rrp so they can discount it. Very annoying. Kids stuff is ok but again, ludicrously expensive given the quality of it.
I agree it used to be really good. The quality was always far better than other shops of the same ilk. We have one here - in the Middle East - that is much better. It's like the one back home, but from a few years back.
M&Co has always been a bit hit and miss, but I find that when they are good they are very good. I wore the plum cord 60s style tunic I bought from there to death last winter, and I've just bought the same style in teal with their 25% off promotion this weekend. I didn't see anything else I fancied though, although I love their jeans.
I had an absolute ton of lovely stuff for ds when he was small (he's nearly 2). In the last year, they've trebled the price but kept the Primark quality as well as succumbing to the awful "sludge for boys, flouro pink for girls" tripe
