if it truly was a pricing error she could have refused sale on that grounds alone. Even if it wasn't stores have the right to refuse to sell to someone.
there was plenty she could have done if she cared, but they don't care where the money comes from so long as they get it.
I'm not mad for me as I already had my own Trypticon months ago and secured two more on Thursday (spare for me and one to offer up at cost to other fans, which is being picked up Monday, sorry guys) I'm mad for the people here that missed out on owning a piece of transformers history for a smashing good price.
Anyway I'll shut up about this matter now and wash my hands of it, just goes further to proving I made the right choice to ditch brick and mortars wherever possible in favour of online retail (I still count a physical stores online store as part of the brick n mortar package)
