With orders of $25 or more, Amazon offers Prime members the Post-it Flags with On-the-Go Dispenser for $1.99. Clip the $1 off coupon on the product page to cut the price to 99 cents. With free shipping, that's tied with our mention from last week and $4 below the lowest total price we could find for a similar quantity elsewhere. (Non-members can spend $35 or more to qualify for free shipping.) It includes 20 of each color flag: blue, green, yellow, orange, and red.

Note that this item is part of Amazon's "Add-on program"; it can only be purchased with an order of $25 or more.
