Help finding bag for my bday

Hi! My time has come!!!! I'm getting my first LV for my 30th bday on Aplril 26. I want a big tote. I'm wondering if I can get some recommendations on places to get gently used bags? I'm planning on getting a brand new one from the website, but if there is one similar to what I'm looking for, that u can't tell has been used, for a significantly cheaper price then I don't see why i wouldn't go that route. I'm not sure what the best sites are. Any help? Thank you 😊
