Last month it was Sam's Club hoping to sign up new members with some freebies on Groupon. Now it's Costco's turn, also on Groupon.

Here's the deal. Pay $60 for a Gold Star membership (the regular price), but get four freebies to sweeten the offer.
Freebie #1: A $20 Costco cash card
Freebie #2: Three coupons worth about $36, including free Kirkland Signature paper towels ($15 value), free VitaRain Zero Flavored Water ($10 value)and a free Food Court whole pizza ($10 value).
Freebie #3: $25 off an order of $250 or more on Costco.com
Freebie #4: $75 Costco cash card toward Costco travel to the Caribbean, Costa Rica, Europe, Hawaii, Mexico or the South Pacific (cruises excluded).
The offer is good only for new members. Prior members had to have canceled before April 1, 2017 or are not eligible.
More fine print: You must redeem your voucher for the membership prior to Nov. 1. If the voucher is not redeemed, you receive the amount paid for the voucher. Most of the freebie vouchers expire Jan. 31, 2018, The travel cash card expires Dec. 31, 2017 although travel does not have to be completed by then. Coupons are mailed 4-6 weeks after validation in the store.
