To find the total number of DVDs Billy sold, we need to calculate the number of DVDs bought by each group of customers and then add them together.

1.  **First 3 customers:** Each buys 1 DVD.
    $3 \text{ customers} \times 1 \text{ DVD/customer} = 3 \text{ DVDs}$

2.  **Next 2 customers:** Each buys 2 DVDs.
    $2 \text{ customers} \times 2 \text{ DVDs/customer} = 4 \text{ DVDs}$

3.  **Last 3 customers:** They buy 0 DVDs.
    $3 \text{ customers} \times 0 \text{ DVDs/customer} = 0 \text{ DVDs}$

4.  **Total:** Add the DVDs from all groups.
    $3 + 4 + 0 = 7 \text{ DVDs}$

\boxed{7}
