In regards to the sale of 20% off immune health products, there was a major problem with checkout. All of the items listed as part of the sale indicated 20% off except one. There were 5 items in the cart when I checked out and after I applied the code 23ILLUME only 3 of the items had the 20% applied. Nowhere on the site does indicate a limit to the number of items one can buy and use the 20%. What I did was delete the items on sale and just have the items without the discount in the cart. The result was no 20 % discount. I made a purchase but not the one I originally made. The fact there are no phone lines available means if there is a problem you are out of recourse. For over 20 years I have been a customer of Lifesource with few issues, but this is problematic when you are expecting a discount that does not occur.
