Just chipping in, my gf has 4 phones, her purpose is to take advantage of multiple accounts to accumulate all those deals and points for discount and freebies, whenever she buys something, it is almost free because of all the points she accumulated by hunting down the deals and games in the online shopping apps. This behavior of hers saved everyone a lot of money when buying things we need, and I appreciate that. It's her hobby too so she is enjoying doing it, sometimes she even prioritize doing it when I am right beside her, need to wait her finish before we can have our spicy time.
