Tzippy,
These gemachs are great. Many gemachs have “suggested” prices, because their purpose as a “gemach” is to help out financially. I think a “suggested” price makes the renter feel really comfortable if they are only able to pay less, and I give a lot of credit to all of those gemachs (from flowers to gowns and beyond) that give so much of their time for such a chessed, usually l’ilui nishmas a loved one.
