Ebay has a tiered promo with coupon code SHOPANDSAVE. One of the eligible sellers has several CMF lots, including factory sealed boxes of Series 27 for $154, before coupon savings ($10 off post tax for orders $150+). Ends up being 20% off versus buying a sealed case at retail. You can buy multiples to get the seller savings and hit another tier, but the tiers are less lucrative the higher the purchase total (i havent done the math to see if the bulk discounts offered by the vendor offset the loss in savings from the coupon).
