Walgreens Coupon Questions

Hi, I'm new to Walgreens couponing and still figuring out how coupons interact and stack. I have the earn $5 when you spend $20 on P&G products and the earn $10 when you spend $35. Am I able to stack these in one transaction? I have another coupon deal to do after using the make 2 purchases of $10 and get $5 in Walgreens cash and want to make sure these transactions work before going to the store. None of my stores have self checkout so I want to make sure I do it right.

The exact deal I am looking at doing is 2 Dove deep moisture body washes for $7 each, 1 Gain Ultra Oxi Liquid 154 fl oz. for $15.99, and 1 Tide Ultra Oxi Liquid 37 fl oz. for $5.49. I have the $7 off dove, $1.50 off tide, and $4 off gain coupons applied to these items. Would this qualify for the P&G and spend 35 deal? Basically would I get the $5 and $10 Walgreens cash rewards?

My second transaction would be 2 Oral B toothbrushes for $3 each and 2 Colgate toothpaste for $4.50 each. I have the $3 Oral B coupon and $4 Colgate coupon. These are over $10 before coupons and was wondering if this counts for make 2 purchases of $10 and get $5 in Walgreens cash.

Any help is appreciated, I'm struggling to learn Walgreens couponing
