ABSOLUTELY.
It gives us a chance to try new restaurants and eat out very reasonably. It is even great for fast food deals, miniature golf, local theaters, attractions, etc. There are coupons for stores too - usually Sharper Image, New York + Company, Foot Locker, Champs, etc.
Last year I bought mine on ebay for $17 - brand new. Check there for your area.
And usually the money is going to a good cause ~ They also sell them at many thrift stores and at Sam's Club. (Perhaps others too.) On the Entertainment book website, they are offering free shipping now.
I get my investment back very quickly. And as a member, you are entitled to additional discounts available on their website. Good luck.
