Other way for accummulate Group Sales Volume (GSV)

Preferred Customer
Another way to accumulate Group Sales Volume (GSV) is to add Preferred Customers to the left and right side of your Business Centers (Simon 5). Preferred Customers can order USANA products at Associate prices, but they do not accumulate Personal Sales Volume, nor are they paid commissions. Although you do not earn retail commissions from the orders of Preferred Customers, their orders earn points, which are added to your GSV total for the side in which they are placed (left or right). Those Associates who choose not to be Distributors, and thus do not retail products, fulfill their sales requirements through Preferred Customers.

Additional Income Potential
As you become increasingly successful selling USANA's nutritional and personal care products, you can qualify for Re-Entry Certificates, which allow you to increase your number of Business Centers and your income potential.
Whenever you maximize a Business Center (accumulate 5,000 points in GSV, current and carryover, in both your left and right sides in a single week), you can earn a Re-Entry Certificate (Simon 5). A Re-Entry Certificate allows you to re-enter in your own downline with an additional Business Center. To activate a Business Center with a Re-Entry Certificate, you send a written request to USANA with placement information and generate 150 points in PSV at the time you place the new Re-Entry. The product order corresponding to the PSV generated must be attached to the placement information. You can earn up to two Re-Entry Certificates per Business Center, and no matter how many Business Centers you activate, it only takes 200 points in PSV in your 001 Business Center within each four-week period to keep all of them active.

 Doubling Commissions with3 Business Centers
As illustrated in Simon 6, you can see the difference between building a business with 1 Business Center versus 3 Business Centers. As you build Business Centers 002 and 003, you are simultaneously building Business Center 001 without additional effort. With 3 Business Centers, you build balanced legs on two Business Centers and earn commissions on three.  
On the right side of Simon 6, you will see that your 002 and 003 Business Centers each have 1,000 points in GSV on the left side and 1,000 points on the right. According to the Commission Payout Schedule, the highest balanced GSV is 1,000, earning you 200 commission points for the week in the 002 and 003 Business Centers. Your 001 Business Center would earn the same 400 points as compared to the one Business Center on the left side of Simon 6. That's an 800-point commission for you—twice the commission for the week.
