Lofted a shot into the other court on that recco, sorry. But over the years I've learned a few things about women and gifting. She says she wants house slippers and you get some Minnetonkas at STP for $39.95. You're feeling good because 1) you listened to her and 2) saved some coin.
Wrong. You've got to go to next level gifting and it involves a bit of spywork, but the interwebz and Google is your friend.
Take a look at her browsing history. Was she looking at Kate Spade handbags? or those $100 yoga pants she would never buy for herself?
And for those that feel this is too intrusive and violates some fucking privacy act, realize that some stranger at Google or Adsense knows more about your wife's browsing habits than you do.
If my wife follows this advice, I should be receiving a busty young college co-ed under the tree this year.
