Best place to resell?

I managed to snag an LV x TM all in bb, but after a few weeks of letting it sit on my shelf I’ve come to accept that it just isn’t my style. I’m petrified of reselling and getting scammed, any tips on good sites to do this ? TIA! The alternative would be to return it but I feel bad bc my SA did a lot to get it for me.

Update: thanks for the advice, she went back to the store today and my sweet SA had someone already coming in for her!
