One customer bought 5 prints on April, 24th. I have a "Buy 5 Get 1 free" promo so I tried to contact her to ask which free print she would like. I sent 2 convos and 1 email and didn't get any answer. In the last message, I told her that if I didn't hear from her today, I would select a free print for her and send the whole thing tomorrow. Do you think that's reasonable or should I wait more ? My initial processing time stated today as the shipping date.
