Swaddleaze infant size - problems getting hold of it? experience of "buy 4 baby"?

[Sanguine]

Our little lad loves to be swaddled but he's grown out of his miracle blanket. We thought that the swaddleaze blankets looked good as a kind of transition to a sleeping bag, so we tried a few websites only to find that the infant size (3-6 months) was unavailable or sold out on most of them. We eventually found a site called buy 4 baby that claimed to have some, so I placed my order a week ago last saturday. I got a receipt from paypal, but no information about dispatch. On the website it said it would be delivered in 7 working days. I e-mailed them, but got no response, and I phoned them today but only got an answer machine and no one called me back. Now I'm wondering if there is a supply problem for them. Does anyone know if this is the case? and has anyone ever bought anything from buy 4 baby? I'm worrying that these things are unavailable and this company have taken my money with no intention of coming up with the goods!
