Puritan's Pride brand vitamin suppliments?, any good?

Hi, I just recieved a flier with a great offer of 89 cents each of several supplements and want to order. I was just wondering if anyone here has any idea if these are good products, and if the experience of ordering from them was a good one, thanks. I am pretty new to supplements so if you care to add your must haves,, and share, that would be great too!! thanks ,
