I had no idea dry cleaning was so primo in SA!

I can't imagine why. That being said, I've shopped dry cleaning places and I have to say that the "bargain" places have done some really awful jobs on our cleaning.
Pricing is hard because it depends on your personal items. Some offer cheap men's shirts, but women's blouses are outrageous! So you have to really look at your own personal cleaning menu and shop accordingly.
Some of the chains offer "coupons" for certain items. Slater White is one for example. Access their general web site and print out the coupon. We also used to like Dutch Boy....but we don't have a location near us now.
