This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Last time I was looking, their prices were competitive with DickBlick. Also, there's a Utrecht brick-and-mortar near me, so I use the website to see what I want, quantities, colors, item numbers, and ballpark prices and then go to the store to buy it.
