Happy to pay $6.64 or thereabouts in the day, but I think it is unreasonable to be expected to know it's in U.S dollars when the cost is described as $5.00 in an ostensibly local context. It wouldn't have hurt to stipulate with a U.S in front of it.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
