One of my favorite low priced promotional products is the sticky note pad. Everyone uses them and they are easy to send in the mail. Bic has a special on the 4"w x 3"h pad, 25 sheets, until the end of August. For a quantity of 500 they are .60 each but you then get 500 free! Plus, they are printed in full color 4 color process. The above photo shows how you can print a halftone of a photo in the background and then 100% ink with a logo and/or copy. Did you know that you can send a 3" x 3" pad in an envelope with a letter for no additional postage. Why not send one with you next letter and keep your company in front of your client for many days to come. They may throw out the letter but I guarantee that they will keep the sticky note pad.
