which would you choose?

I didn't know overstock has current authenticity issues?
Either way, to the OP, I'd be very careful with a light gaufre. The lambskin on this bag is prone to color transfer and scratches. I have the same exact bag but in light pink. The color was faded and it had scuff marks on the corners when I got it. The bag has stayed in pretty much the same condition because I hardly use it. Don't get me wrong, though. I love my bag, but it is delicate so it warrants a warning.
As for the price, the retail on this bag was $18xx. However, I believe it was part of the previous sales and I'm willing to bet that if it was, then it was sold for much less than $1200 overstock is asking for.
But then you have to factor in how much you really like this bag (is it something you're willing to pay $1200 for?) and how often you'll see it in the secondary market.
I prefer this bag over the Miu Miu.
 
Love the Prada gauffre - but I agree it's a light color and you really can't use it as an everday bag - I've seen the Prada in Black & Red that would be great for everyday.
I've ordered from Overstock and haven't had any issues.
