Same here... last month I shot in the .22 match, first PRS style match I ever attended and it was a blast. Everyone was nice enough to let me try their bags, and afterwards I wanted to drive into CS and pick one up but like you said, they are closed Saturdays...
I am planning to go shoot the .22 match again tomorrow, and I never got around to finding a reason to go to CS to buy one. Not really something I want to buy online, since it would be nice to touch and feel them before plopping down $75 on a bag.
