Some common selling strategies are (choose all that apply): door-to-door sales, telemarketing sales, forced sales and Web-based sales.

1. Door-to-door sales: This strategy involves a salesperson visiting potential customers at their homes or places of business to sell products or services directly.

2. Telemarketing sales: This involves contacting potential customers over the phone to sell products or services. Telemarketers can either cold call (call without prior contact) or follow up with people who have shown interest in the product or service.

3. Web-based sales: This strategy utilizes the internet for selling products or services. Businesses create online platforms such as websites or use third-party e-commerce platforms to reach customers globally.

"Forced sales" is generally not recognized as a legitimate selling strategy. It implies coercion or manipulation, which is unethical and can be illegal. Legitimate selling must involve the customer's consent and a willingness to purchase, free from undue pressure or deception.
