Demon Tweeks are sneaky though!
I ordered my Heusinkveld Pro's with base plate from them 2 weeks ago, in stock and paid for Saturday next day delivery. They didn't ship them, so I called only to be told there's a 2 week lead time.. I asked for a refund.
Checked eBay, found them for next day delivery, what a surprise when it was Demon Tweeks selling them!
Ordered from Heusinkveld and they arrived 2 days later, but still no refund from Demon Tweeks. Called them again and was told "Oh, yes, we cancelled your order but didn't issue a refund!" so a week after I cancelled I finally got my money back.
I've used Demon Tweeks for the last 28 years, but they have gotten worse over the last 5 years and I doubt I'll use them again unless I can't source elsewhere.
I'd just order from Heusinkveld direct, then at least you're dealing with the organ grinder and not the monkey!
I previously had Fanatec Clubsport V3's and the Heusinkveld Pro's are far superior but they are almost double the price, despite that I can't recommend them highly enough.
