I have been using Staples 110 pound card stock for ages. I periodically create postcards for a medium sized mailing program and this product fits the bill. It is reasonably priced but the quality is as good as the more expensive stuff. One nice thing is that it is readily available in the store so I can pick it up if I am in the area. It is also available online so that if I am too busy to get to the store it arrives the next day. I have quit using the more expensive brands as they do not offer an advantage over the Staples paper.
Nice paper but expensive! I recommend it if you need cardstock but shop around. I was under the gun and ended up paying over thirteen bucks for a ream of paper.
