1. A Spa Day - So this idea costs a bit, but it might be worth it. Give her anything from a coupon for one massage, to a coupon for a whole day at the spa. She'll come back relaxed and thanking you!
2. A Quick Get-Away - This is particularly valuable if you have kids. Find a babysitter and plan a quick get-away without telling her. She'll love the surprise and the two of you will enjoy your time away together.
3. Game Night - If she enjoys playing games, you can purchase a new, fun game for the two of you to enjoy. You can even secretly invite over a few friends and have a game night together.
4. Gym Membership - If you think she'd enjoy getting this gift and it won't offend her, buy her a one year gym membership. She'll be thinking of you as she gets healthier! If this is too much, you can buy a basket and fill it with gym supplies such as a workout outfit, a Bender Ball, a bottle of water and some ankle weights.
Hope these ideas help. It's almost Valentine's Day, so get shopping if you are still empty handed!
