Already started down that road, others at the gallery use bags and I was going to make the switch, but the best I could find was like $100 for 100 bags, which may last a year before I have to order more, the shrink wrap covering looked better by far to me, was cheaper at least by half. A roll of shrink wrap usually lasts several years. I just didn't want to come up with $100 at once if I could help it. I don't like the way the others work looks in those bags, the surfaces are warped and reflect light across an uneven surface, they are sort of loose, and to me they just look sloppy. I guess if it was cheaper than shrink wrap I would go for it. By the way, I do get my mats from ClearBags.

If the matted prints are standard sizes, maybe consider using crystal clear bags from Clear Bags. Easier to use, specifically made for art work and will not damage the work, easy to re bag if a bag gets dirty, can be bought in bulk so generally economical.
