A really wonderful site, great filters, great price tracking. The only thing I'd wish for would be the ability to exclude all those amazon.com shops from the results (everyone from amazons marketplace seems to be listed as a distinct shop there).
The only feature that's missing is a toggle that will show you all their products in the product database including those with no offers. Right now you will only find them when you search for their names but you can't list all 5k (5120x2880) monitors for example, only the very few models that are still being sold today.
