Currently Wiggle (and Chain Reaction) have quite a few good deals, and a handful of ludicrously cheap deals. As times progresses, there's obviously an increasing risk that they may go totally bust and an order may not be delivered, but as others have said it's moderately likely that we would get our money back, in that scenario.
I've ordered a handful of very cheap items, between 50% and 70% off, a pair of shoes, shorts and tights, most of them dhb branded, but not entirely. Everything arrived quite rapidly and exactly as ordered.
I then took an even deeper plunge, and ordered a Vitus e-bike at 40% off. The normal price was way beyond what I'd spend, but at that discount it was merely expensive. It's a very nice bike, and I'm very happy with it.
There are some very good deals to be had, but quite often you'll find clothes and bikes only have the cheap prices for the less desirable sizes, or those cheap offers are now out of stock, with the phrase "Stock expected soon", although I have my doubts about that!
