Last year I ordered a Feinwerkbau 800 from buinger shooting in Germany the postage was a bit pricey but saved about £500 overall. The day after I placed to order I was sent an email asking for proof of age. I scanned and emails my passport. The day after that I had an email saying it was dispatched. It took 10 days in total for it to arrive from the day I placed the order.
I have since also orderd accessories and bulk pellets from buinger and Tec-hro saving a lot of money. Smaller items usually turn up in 4 or 5 working days.
