This one’s a bit tricky. If you move your mouse over the wisk bottle, 3 hexagons will show up. Click the hexagon that says “Request A Sample” and it’ll take you to the signup form. Sam’s Club Member ID isn’t required, but if they ask any 9 numbers will do. For example 456654896 Please allow 4-6 weeks for your sample to arrive.
