If I wanted to purchase another Turbo Mega-Flow mask in the future, would I need to purchase it from you exclusively?

You can get the patented Turbo Dual Megaflow Mask only with us. When you buy along with the combo, you get it for $75. Individually, they are $249 + shipping. When you purchase it with the combo, the price is $75. If you choose to buy it separately, the cost is $249 plus shipping. However, if you are a Combo customer and wish to buy additional masks separately later on, we can offer them to you for $75 (or the prevailing price at that time) plus shipping. We suggest buying extra masks when you purchase the combo to save on shipping costs. Many of our customers buy 3 or 4 additional masks for their family members when they purchase the combo.
