I take it there is no rule against posting referral links here, since there is a similar thread for Bing Rewards. So, I have a referral link for Google Express:
https://google.com/express/invite/SQBF5S3BSThat will get you $15 the first order, and I also get a $15 coupon. For those who don't know, this is Googles Same day (or next day) delivery service that delivers stuff from local stores. It is not obviously mustachian, but combined with their three month free trial, this basically means $15 dollars off anything they deliver (which is quite a lot of things, including items from Costco). Prices are guaranteed to be the same as in the stores, so you don't need to worry about being charged extra in a stealth way. Also, they've been promoting the service with so many coupons that I think I am up about $85 despite having paid for some deliveries.
