Query: Please Don't Waste Your Money

I purchased two 25-packs because of lower prices and free shipment but it was a bad mistake. I had too many coasters from the 1st pack. I am about 50% with the 2nd pack which has been trouble-free so far.After some research my next purchase will be Verbatim - based on positive customer feedback.
