Strange. What did you order?
I've bought a few things from them - menzerna powerlock, hex logic spot pads and r222 wax. Three orders over the last three weeks and they've all arrived within 48 hours of ordering! With each order, I've put a message to add "deliver to addressee only" on to the outside and they've conplied without any issues.
Have they taken payment? Have they sent an email to say it's been despatched? Have you had a look at the order in your account to see if they're waiting for stock? What did you buy?
