If you prefer not to make quilts but sew garments (dresses and shorts) Nancy's Notions has a site for dresses/shorts for kids. Also check with your local nursery at the hospitals and see if they accept small quilts, hats etc.. Many of the local shelters take quilts also for at risk families. Dog Rescues are always in need of quilts for the dogs to lay on or make their own.
ITs a shame that a shop wouldn't know such information, maybe as suggested; make a list and ask the owner/employees to make it available for people who do want to make a quilt and send it on to a charity.
