The best thread I found covering Maelstrom is on Dakka:
Maelstrom Games taking the biscuit? - Page 32 - Forum - DakkaDakkaif you don't want to wade through 30+ pages, here is a quick summary:
1) Maelstrom had massive debts (£100s of thousands)
2) They have been cut off by many of their suppliers (including GW, Wryd and others)
3) Paypal stopped dealing with them
4) They were not shipping anything that was not in stock, just keeping people's money
5) they ran an increasingly desperate series of sales (up to 80%) to clear remaining stock.
6) the website is now disabled
7) they "sold off" the gaming store and banelegions ranges so these are still running (possible until the receivers get them....), although the same guy runs all three.
8 ) they refused to reply to any form of contact (email/phone/recorded letter)
They have now almost certainly gone bust.
If you ordered stuff not in stock I would suggest filing a PayPal complaint or contest the charges on your credit card- you won't see your stuff
If you ordered stuff from the sale you may get it if it is now in the post.
I submitted a claim through PayPal to get my money for Dark Vengance back. I also got all the stuff I ordered from the clearance sales with no problems.
Avoid Maelstrom games, the Eye of the storm webstore and possibly Mierce Miniatures (who produce Banelegions) like the Plague. Lots of people have lost money and there was a fair amount of deception and dodgy practices going on at the end (false reasons for the sales etc). I am not sure if they were incompetant or fradulent, but either way, you don't want to trust them with your money.
