Swing boughten for baby shower that I didn’t necessarily want

My aunt bought me a fisher price swing for my baby shower. We think it was from a liquidation place, or an outlet that carries all discontinued Walmart/Costco stuff bc the box is damaged and doesn’t look brand new. I had a swing on my registry that I would prefer, as the base comes off and just sits on the floor as a bouncer. So a 2 in 1 deal is better.

I haven’t been able to find the exact swing online anywhere (probably because it’s discontinued). I want the swing I originally put on my registry.

Should I try taking it back to walmart to see if maybe it’s still in their database, and get an in store credit. Or do I just try to sell it?

Also does that make me seem selfish or ungrateful..
