looks like sinnovator and uberkinky's parent company N.E. Services Limited has filed for bankruptcy. it sounds like both brands are shutting down. i have seen a couple people mention they cannot purchase from sinnovator & get an "in administration" response when emailing.

this is the listing for sinnovator auctions (gear, probably stock ("samples")) but no items are visible yet: https://www.i-bidder.com/en-gb/auction-catalogues/gilbert-baitson/catalogue-id-ibgi11146
sounds like they may do shipping?
