Thanks, Bengal. As most tailors just take half down, as a follow-up -
1. If I put down 1,200 gbp (1,000 gbp + 200 gbp VAT) down for the deposit in Jan 2014
2. And pay the remaining 1,200 gbp when I pick up the suit in August 2014
Won't HM Customs only refund the second 200 gbp, as the first bill has expired? When I walk out of the country with the goods in August, the only valid current invoice I'll have is for the second 1,200 gbp.
Apologies if I'm being obtuse here.
