It's a store. They ship stuff all the time, even if they don't have e-commerce operations. Of course, they have a fedex or UPS account. Stores get a constant flow of deliveries and ship between locations, to and from wholesale, etc...
I'm just saying: I bought mountains of stuff from various sellers, shops, etc... and was NEVER quoted $150 for shipping to the US. Rarely do I see shipping above GBP 50...
