One of the first bags that I purchased after moving to US was Kenneth Cole Reaction. I got it from Marshalls for $25 plus tax. It was small but made from leather. I've used it for many years and still occasionally use it when I travel and don't want to attract attention. I should probably get rid of it but it has certain sentimental value to me at this point.
It took me a while to move past $100 point. I had expensive footwear but not purses, it just was not my thing. And it's not like I could not afford them. I was just blissfully ignorant, I guess. I spent tons of money of travel, dining out and shows.
My first expensive purse was small Gucci bag that I bought for myself for my birthday since DH forgot to give me anything

and I was going to make it right

. I did not acquire any bags until I discovered tPF. And now I have two BVs, which both were over $1K, and a few Goldenbleu bags.
My MIL loves purses but with the exception of Botkier that I gifted her keeps her bags relatively cheap. Mostly Liz Claiborn and such. She also can afford to spend more on a purse but does not see the need.
So, yes, while I find these statistics surprising I believe them. Same as when I found out income for an average family in US.
