ecommerce platform or blog button

Hi!

I want to sell few products, up to 5, on my blog. How can I do this?
It’s better to make an online store, separate from the blog?

The smooth of operations and the happiness of my visitors and customers has priority. I want to offer what I’d like to find visiting an online store, very small store, but significant.
Please help me find the best solutions.

Thank you and have a great day!

Best,
Crina
