I'm an adult male, and as such, have learned to never buy clothing for women unless something is specifically requested.

My mom recently had a gastric bypass, and has lost a ton of weight. She's a little hard on funds, so she hasn't bought any news clothes yet. As lame as it is as a gift, I want to get her a gift card to someplace she can get the most bang for her buck to replace a lot of her wardrobe. I'm like 95% certain she doesn't care about the label or branding, just clothes that fit well for a good price.

What would be a good option here? Something as simple as Walmart? Or is Target, TJ Max, Marshall's, etc etc a better bet?
