I agree with everyone here in that I think you should definitely wait for your dream Marcie! It's easy to settle when the price is right on something that happens to be right in front of you, but if you're not in love with it, it'll just end up in the closet and you'll end up spending twice as much, once on the "settle" bag, and once on the dream bag that you know you're gonna inevitably get down the line because it's your dream bag!
On a side note, I see that the tag on the bag in that listing says "Light Tan"... I've never seen "Light" tan in person but I know that "Tan" IRL is a lot more orange-y than photos depict sometimes, which was a dealbreaker for me. I prefer a much softer, true camel myself! (I wish the seller would just call it the name on the tag. Chloe colors are confusing as all hell as it is already!)
On another side note, I really think a Black Marcie at a reasonable price is something that could easily come up in the future, especially with the fall season coming up. Keep a close eye on Erica's selection at ******... she has a GREAT Chloe selection and prices everything a good $500 less than retail, plus has promo codes all the time!!
