That's what, fifty bucks? For fricken PERI? I wouldn't even pay that for Ian and Barbara combined.
It should be cheaper with the exchange. For example, I've never seen Mike's charge more than $35 USD for two figure sets like the First/Dalek, Second/Cyberman, Third/Dalek, etc.
But yeah, these should be priced at $25-30 USD maximum in my opinion.
Well, once you figure in S&H, the price could be anywhere between $42-48 USD, depending on where you get them from...
