I ordered an indexing arm from them yesterday and paid the xtra 38p for 1st class postage and was amased it arrived this morning ..... we're slightly in the sticks and I think the PO often choose to forget we're here on a Saturday so I'd say it's more than likely it's down to Yodel rather the JSR ... that said if their chosen courier continually fail to deliver they need to look at using someone else.
Really interested to see what your feedback is on the scope though as I've been looking at one of these for a while, I was also interested in theIr 3-9x32 Bugbuster copy but it's been out of stock for literally months now which is a shame
