Coin operated laundry

My SO and I are currently looking for an apartment and it seems there is absolutely nothing with laundry in-suite, so coin operated laundry machines it is for us. For anybody else in a similar situation, about how much weekly do you spend on washing? The whole point of cloth diapering for us is to save money after all

It is what it is I suppose!

Any tips on how to go longer between washes?
