Back again if you haven't yet requested yours! Look what showed up in my mailbox this weekend!
I went here and requested a free sample of Persil ProClean Discs, and not only did they send me two samples instead of one, they also sent out a $2 off coupon!
Persil ProClean Detergent is priced around $4.94 per tub at HEB and Walmart, so my next tub will be just $2.94 after Q.
Make sure to request your free sample while supplies last! You can also enter the Deep Clean Challenge Sweepstakes, which has a grand prize of $5000 in cash AND a year's worth of detergent. That is definitely worth the five seconds it takes to enter if you ask me.
