depending on the size and need (ie if its for a sling) you can get d-rings at a hardware store!
joanns.com (its the same as the big craft store)
have you tried a walmart at all??
for that matter - email me [email protected] as to what exactly you need and i can find them and mail them to you; all i'll charge for shipping is the actual postage unlike stores. they'll charge you six bucks to mail a 90 cent item : )
