No, can get away purchasing only $200 wholesale ($400 retail) a year, but it has to be all in 1 order. Let's say you order tomorrow a $200 wholesale order. Your 50% discount would be good for the rest of Jan, Feb and March. However, on April 1st, IF you needed to order, you would need to, again, buy $200 wholesale to get your discount. But you don't have to order that often, as long as you order within 12 calendar months (in this example by Dec 31, 2011), and order $200 wholesale -you are good. Remember, shipping is $8 or $9 an order and you must pay sales tax for the retail value (not just wholesale).
I buy through another 'personal use' consultant who allows me to help her reach her quotas at cost. I buy about $200 wholesale a year through her and if she chose to get out, I would return to MK as a personal use consultant. I save lots of money this way by getting consultant samples. For example, Microderm kit is $55 retail, or $27 wholesale. But I can buy a sample packs for $2 each and if I buy $8 worth of samples = full size product quantity! I like buying through her so I can get the quarterly special edition products without buying another $180 worth of stuff I don't need
Ebay is a cheap source, but I have found the products to be old. Might still be 'good' but, I don't like anything to put anything on my face that is over 2 years old (google for manufacturing date code stamped on all MK products).
