In most of the events that I have attended to, companies always give away bags (with stuff inside) as tokens to the media and even bloggers who took time to come and cover events. Most of the companies give away eco-bags, notepads and personalized pens, even mugs and USBs with logos of their companies which I think best promotes their products and services.
Atlhough blogging and traditional advertising have been very efficient in reaching out to the market, these types of promotional items are much appreciated by the consumers because these are things that we can use and re-use.
At least, that saves me money instead of buying new supplies of pens and notepads – at the same time helping the sponsors promote their brands.
I always see businesses in the malls which offer this type of printing services, but the http://www.amsterdamprinting.com/ is one online source which offers good items and discounts too.
