Evening peeps.  So I sent my plans into wunda to get a design done, knowing full well there is a £50 charge for the drawings, ok cool bananas.  So I received an invoice and it turns out the cost has gone up to £100 refunded from your purchase.  So am I being bent over ? do I just pay it as their stuff is good and it’s not worth the agro running around looking for other quotes, there quote has come in £1000 cheaper than continental underfloor.    What ya reckon @Nick
