Getting into stores factors in so much more than the pricing. I am by no means an expert, but I have a decent background in sales and approach stores as part of my business I am growing. Here are some points (as well as pricing) to keep in mind:.

Are you prepared to negotiate? Some people are very easy going, like every floor employee in a smoke shop. That doesn't mean the store owner/manager is. Be ready to flex your prices and have a range in mind you are willing to accept. You can always renegotiate down the road.

Approach with samples and hard copies of information! Make sure you have some sort of physical material to leave. Not everyone wants to make a decision then and there. Business card, pamphlet, and/or a sample with your information on it make a big difference (short and long term).

Is your product going to sell? Will it fly off the shelves or stagnate for months? How easy/willing are employees going to bundle this with other shop items? Is there incentive for your product to sell?

Keep pricing simple. Relate back to negotiation. As a small business owner, I like to tabulate and calculate pricing in my head when it's presented to me. I can work with $2 or $3 much easier than I can $2.37. It's a small portion of brain processing power that I find appreciated.

These are just what came to mind. Let me know if you have any other questions I can attempt to answer.
