Can't check out....

... I've been trying since Friday night Nov 16th to make a purchase for the PreBlackFriday sales event (limited quantities) and I keep getting a message page "temporarily can't find my destination page"  ARGH!!!!! 
I've tried several browsers, logged on from home, from work & a neighbors computer only to get the same message.  I even emailed Walmarts customer service & another through the comments page they have for suggestions. The emails I got back were canned responses to check my browser (I already told them I had).  They also commented that they don't know if any glitches at this time.  Hey... I just told them they had one! 
I've made many purchases through their website with no problems until now.
