Let's break down the problem step by step:

1. Billy has 8 customers on Tuesday.
2. The first 3 customers each buy 1 DVD.
   - DVDs sold to first 3 customers: 3 customers × 1 DVD/customer = 3 DVDs.
3. The next 2 customers each buy 2 DVDs.
   - DVDs sold to next 2 customers: 2 customers × 2 DVDs/customer = 4 DVDs.
4. The last 3 customers don't buy any DVDs.
   - DVDs sold to last 3 customers: 3 customers × 0 DVDs/customer = 0 DVDs.

Now, add up the DVDs sold to all customers:
- Total DVDs sold = 3 DVDs (from first 3 customers) + 4 DVDs (from next 2 customers) + 0 DVDs (from last 3 customers) = 7 DVDs.

\boxed{7}
