@TwoLanguageTrainer asks
seller lowered another copy after I bought mine. do i ask for money back?
Jeff answers
I'd check whether the seller offered a price-adjustment policy, rather than assuming one applies. Our app can help you understand the current reference, but a later change doesn't automatically rewrite a completed deal. If your original purchase was accurately described, decide whether asking politely is worth the conversation.
