What will be the affordable best gift for a boss?

Not knowing your boss makes it hard to come up with a gift. What does he like to do? If he likes ball games or live shows or something like that, how about tickets for him and his wife? Or a gift certificate to a dinner out? I guess part of it depends on what you mean by "affordable." We all have our definitions of that! If he works late at the office, get him a thermos cup for hot or cold drinks. Or if he's a fan of Nascar or a football team or is interested in wildlife or whatever... there are desk sets with logos on them and some of them are fairly inexpensive.

Buy him a gift card & let him pick out what he wants. I like to get them myself but haven't ever gotten but one from on of my customers a long time ago.

Hi. I suppose your boss uses a lot of ballpens. I think giving him a nice penholder would be great. He will surely use it for his pens. Choose a penholder that can accommodate several pens and not just one or two.
