If you are not using memo clips as part of your promotional campaign, then you should start thinking about why these are necessary. You see, when it comes to promotional items you need to think about what they are associated with so that you know what your brand or logo will be associated with if you use those items. In the case of memo clips, your brand or logo would be associated with important compiled information. People don't bother with memo clips unless the items they are putting together are important. That is the kind of thinking you want to happen when you brand or logo is brought up, so not using memo clips could be costing you valuable customers.
