Many shops (like the shop in boise and mine) buy things from Scotland (gbp) and Ireland (euro) both, so both conversions are applicable.

One thing the article DIDN'T mention... The cost of increased fuels and shipping and stricter customs charges adds to the problems with importing goods. I've bought sweaters that cost me $300 for product and paid $200 for shipping and customs. Tell me THAT'S not a killer!
