One time offers in bad time

I sometimes receive “one time” offers in bad time. For example, on Wednesday 6/2/2019 I received an “one time” offer (in that day it contained 5k gems, 3 Gaspar guardian and 50 guardians at 109,99€) in the early morning as soon as I had logged out (and not logged in!) and I noticed it in the evening, after I had come home, and I could not have bought the next morning (also because I bought 9k gems in the previous weekend).

I prefer to receive “one time” offers as soon as I log in (instead of log out), so I’ll better prepared with budget.
