Hey Blue lord I live just south of you in the UK and I can understand your concern I'll be in Denmark visiting some Viking friends after they threw out the Euro (HOORAY!!)
So even though I trust Royal Mail....I don't want a package sat in an office especially with underpaid, underapreciated and overworked people looking at it!
:\
I belive its 7 days for here, depends wether its AIR-Freight or Shipping....Ick...Shipping could mean up to 3 weeks waiting time as the Ship MAY leave on time or may be a day or so late, due to loading or weather
Pray its Air

But I would say 10 days at the most accurate count I can do.
