You may want to consider raising your prices now to factor in the market rate for rent. Since it sounds like you are operating at capacity this is the perfect time to raise prices. When you open a shop and suddenly have much more capacity you don't want to raise prices then since that would reduce demand, plus it would alienate your existing customer base.
Another way to look at this is figuring out who is really benefiting from your rent-free situation. If you are not including market rates for rent in your prices, your customers are receiving 100% of this benefit, and you are getting none of it.
