I definitely see where you're coming from. Having contacted them as you did, it sounds as though you had committed and all they needed to do at that point was invoice you so you could pay them. Sounds to me as though someone else came along and gave them the original price plus shipping and that left you out of the loop. If the seller agreed to sell to you at XXX price then, they should have done so. At the very least, they should have sent you a message and informed you that the item was no longer available. JMHO
