Simply put, it’s a cost saving action. I will wait until my friend will get her SNAP? benefits, and since I saved my from the previous month, we are both able to go on the first weekday of the month. This is planned out that way. If the 1st of the month fell on a weekend or holiday, then we will go the next weekday of the month. This allows her to do her shopping while I also do mine. I am always finished before her, and therefore wait for her. This all sounds normal though, so why not multiple times?
The main reason is cost. If I ask my friend to take me somewhere, then I will compensate her. It is this compensation that I will give every month that is the limiting factor. While I won’t go personal and disclose how much, it is a financial hit where tolerable once a month, won’t be so tolerable bi-weekly, and especially not weekly. Worst case sceanrio, I am walking to Target on a weekly basis, but I am not spending for an automobile. I walk to Target, get my groceries, and walk back home. If I took a bus recently, I might wait for a bus which is usually quicker than walking.
