Based on the images of products, Americopy is just a private label brand, and not a manufacturer of those products. No more than Meritline, which has a house brand of low-price (and to some degree, lower quality) empty CD/DVD cases and supplies. Based off the
Amazon reviews alone, the Americopy black plastic DVD cases are possibly of very low quality, a mix of warped/deformed and broken product. If I had to wager on it, I would even bet the cases smell bad, like cheap petrol products generally do. Some of the jewel cases and sleeves seem to be great deals, however.
Is there a reason you need info on Americopy?
Perhaps we could give some better advice on other manufacturers or stores with media supplies/cases?
