“Owners of promotional products remember the company they came from 87% of the time.”
Low cost might be attractive but it has its drawbacks. Poor quality items might meet your budgetary goals but fall far short in the promotion of your brand or company. With a rate of 87% recall, a cheap or poorly constructed item can have a negative impact that perpetuates itself forward.
Conversely, a promotional product of quality and good manufacture (albeit small) can say a lot about continuing engagement with your brand. Think of it like page ranking. The higher quality the link, the better the link. Well manufactured ad specialties speak well of your brand far into the future.
