If you bought it they did not give it to you at all, they sold it to you. "Give in exchange for" is an oxymoron.

I agree Mrrzy and I acknowledged that when I included i.e. I buy it from them;. "Give in exchange for" was a definition. If the exchange had been for another item, rather than money, the term would have been "swap".

The point is, there are verbs such as to sell, to swap, to lend, etc., which concisely explain under what condition things are given. It doesn't seem unreasonable that there should be a verb for the condition of "give as a gift".
