I think I would sell them but keep one of the bags since it was a nice gesture on their part to try and give you a gift you'd like
I think there should a moratorium on how long you have to keep a gift before you can sell it. I mean, there are purses I buy for myself that I find I don't use after a year. If it's been more than 1 gift-giving cycle (for ex. it's a bag you got 2 birthdays ago), I say sell it. Eventually the gift-giver will probably forget what they got you anyway.
The color is to die for, and I am a big fan of blue.The problem is, the City bag is really not my style, and I didnt really like the color he chose (its this shade of blue: http://images.sabster5.multiply.com...1.JPG?et=jX2c2Clj1fNAxcZLWsqWuA&nmid=60328760)
So now, the bag is still with me and Ive used it five times tops (its been more than three years since he bought it). I cant sell it because it was a gift, but I hardly use it. What a waste.
