Hollister and AE compete directly with Old Navy, not Gap. I think Gap is against A&F.
GAP has been selling overpriced low-quality clothing for a while now. I regularly get GAP gift card from a relative that works there and can’t find anything worth buying. Any department store, even Wal-Mart, will have better quality and selection at a lower price.
Oh, it also doesn’t help that kids have nicknamed GAP “Gay And Proud”
