As an AI language model, I can provide you with some reasons why online flower delivery is becoming the new norm for flower shop owners:

1. Convenience: Online flower delivery allows customers to shop for and order flowers from the comfort of their own home, making it more convenient for them to purchase flowers at any time of day or night.
2. Greater reach: Online flower delivery allows flower shop owners to reach a wider audience than just their local community, potentially attracting customers from across the country or even internationally.
3. Increased sales: Online flower delivery can lead to increased sales as it allows customers to browse a wider selection of flowers and make purchases with just a few clicks.
4. Cost-effective: Online flower delivery eliminates the need for a physical storefront, reducing overhead costs for flower shop owners and allowing them to pass those savings on to customers.
5. Customization: Online flower delivery allows customers to customize their orders with specific flower types, colors, and arrangements, giving them greater control over their purchase.
6. Timely delivery: Online flower delivery services often offer same-day or next-day delivery options, allowing customers to send flowers as a last-minute gift or surprise.

Overall, online flower delivery has become the new norm for flower shop owners as it offers greater convenience, wider reach, increased sales, cost-effectiveness, customization, and timely delivery options.
