Arquest has a couple diaper and training pant studies available. If you qualify for one of their diaper studies you could get free diapers and even a check for your participation in these studies!

Currently Arquest is looking for boys and/or girls wearing Size 1 diapers (up to 14 pounds). They are also looking for girls wearing 3T-4T training pants. To see if you qualify for one of the studies you'll need to call:

1-888-342-7372 ext. 646 (girls)
or
1-888-342-7372 ext. 634 (boys).

If you qualify, they will send you between 1-6 bags of diapers/training pants for free! Plus, after you complete a survey you will receive a $10 check. You can't beat free diapers and $10!
