I don't think that you are wrong regarding credit accounts and the debt that they likely have but I also think Sarah has problems with volume. She can't buy any of the kids one thing they have to have the set. In her warped mind it's better to get 5 shirts for £15 from shein than 2 for £15 from elsewhere as she gets more things for her money irrespective if she has to replace the shein ones every month

I think its been the same with Christmas always even when money perhaps was not as tight... the kids couldn't be started off with a collection of something and then increase it throughout the year they have to have the full collection all at once - it's odd behaviour.
