Kim Kardashian is keeping the blender and the gravy boat, but she's donating twice what she snagged in wedding gifts to a really good charity ... TMZ has learned.
We obtained a letter -- sent to every guest at the Kim K/Kris Humphries wedding. Kim says, "I would like to thank you for your generous and thoughtful wedding gift. It has taken me some time to pull everything together but I wanted to let you know that the money for every gift received by me at my wedding has been donated to the Dream Foundation ..."
Sources tell us ... Kim estimates the total cash value of the all the gifts to be around $100k, but she's cut a check for twice that amount to the Dream Foundation.
Bottom line -- the Dream Foundation gets a lot of cash, and Kim can still make a mean margarita.
