There are a few items in the case that are indicated as "Members Only." So a non-Member visitor would not be able to buy them (the Member would have to be there to buy the item for them). The Dooney and Bourke purses were one of those items.
The brown version of the purse was members only until last month. When we were there, the CM said they were being discontinued, which I guess is why they are now available to be purchased by anyone that is inside the club, to clear the inventory. They are releasing a new Club 33 50th Anniversary version Dooney and Bourke that I'm sure will be limited to Members only.
