I buy most of my pads--Jr. Legal, scratch pads (3x5, 4x6) and post its at large office supply stores like Office Max/Depot. They sell large quanity packs of these items. I have a friend who buys the multi colored stickies at Costco quite inexpensively. I have read on the list that some of these stores carry all-white (non-adhesive)memo cubes. None of the stores in my area do, but yours might.
If you need can't find white memo cubes, in your stores--I sell them on my website at this link:

I also sell other stampables.
