@Richard - This special deal will last as long as GG decides to keep it going. Not indefinitely, but not that short term either, as far as I know. I expect at least through the month of May. I will post to this thread when it ends and take the page down on my site. I believe it applies to anything you might want to get at GG.
@Dale - The code was NOT given to me by GG for my own use. Rather it is a code given to me to put on my website for those that come to my site to use if they want to get a discount on GG items. It may increase traffic to my site (good for me) and reduced cost for those who want to buy something from GG (good for them). Kind of a win win. I view my post as a service to the BPL community more than anything else.
