This is a question for women and mommies only please?

So my mommies birthday is on July 11th In already throwing her a surprise birthday dinner at Bonefish Grill. All her family is coming and her friends. I even was able to get her uncle who lives in Atlanta to come. She loves him so much! And her childhood best friend from Miami to come to the dinner. Whenever their together I become the adult while they play around and just hang. She has no clue. Oh by the way we live in Orlando. I rented part of the restarunt for her dinner, ordered a cake, Ive paid for decorations to be set up (professionally) and I'm paying for her meal my dads and mine. so my question is Shea been hinting around about this 350 dollar purse by Brahmin or whoever it's lol. I know it when is see it. But the thing is I've already spent 600 bucks on the whole party. Plus I promise her uncle and best friend I would reimburse them for gas for coming since it's driving distance and the have relatives they can stay at. So should I get the purse for her. I could afford to buy it for her but it would be a big stretch. I have the money for it but that would only leave me with about 150 in my savings account. This is her big year she turning 50. I've been saving for a long time and I really want to go all out so what do I do????????? HELP!!!!!!!!
