This is a different rebate than the one posted on Phatwallet in this thread by Mistercheap (that is the Made to Save rebate)
To access this new’ish rebate, go to P&G Good Everyday Rebates page, then click on the dropdown menu near the top of the rebate page. It will default to the Made to Save Rebate (which is the prior rebate posted before) but you want to bring up the Good As Gold rebate for submission and reading the T&C’s.

Also, this rebate has a much more pared down list of qualifying P&G brands so look at the picture before going out and spending $50 or $100 worth of products.
I believe you can get two rebates, so long as you’re using completely separate receipts for each rebate, according to the terms and conditions of this offer, italicized below.
Travel/trial size products are not eligible for either Offer. Limitation: You may submit for up to two (2) Offers for Rebates with separate Receipts for each Offer Claim submitted. Limit one (1) Claim per Receipt. Limit two (2) Rewards per person/email address/household. A receipt submitted in this Rebate Program cannot be used in any other Rebate program. You may submit multiple Receipts for any one (1) Offer to spend either $50 or $20 depending on Offer, you must submit separate Receipt(s) for each Offer Claim [so you cannot claim both Offers with the same Receipt(s)]
