Choose a product

T-shirts, key chains, calendars and pens are tried-and-true promotional products: They're inexpensive and everyone needs them. But don't be afraid to get creative, either by choosing a distinctive product in a traditional category or seeking something unusual.

I recommend: Get creative and put your logo on batteries or create a customized deck of playing cards that reinforce your brand. Check out Top Brands or Zagwear for a huge selection of products.

Find the right vendor

Vendors may be called fulfillment houses, promotional products distributors or promotional products consultants. These companies can do as little for you as simply supplying the products, or as much as custom-creating a new product that fits your needs. They can also help with distribution and design and provide customer support services for products like electronics.

I recommend: Find a supplier database at Potentials magazine, or search for suppliers by zip code at Buildapromotion.com.

Go shopping with retailers

Some big-name retailers have an internal department- usually called the special markets or corporate sales division-that handles bulk orders and customization for promotional products.

I recommend: Lands' End has a separate corporate sales site where you can shop for customizable clothing and accessories.

Look for a seal of approval

With your brand's reputation on the line, you want to know you're working with a trusted supplier.

I recommend: It's a good sign if your supplier is affiliated with either the Promotional Products Association International or the Advertising Specialty Institute.
