Collect the following data by conducting individual interviews with the sellers operating in the target area. The best way to identify the maximum number of sellers is to use "snowball sampling" methodology – ask key informants, such as sellers, suppliers or authorities, whether they know about any potential sellers that may or may not sell the promoted product. If you know that there is a very large number of sellers in the target area, use a representative sample of these sellers.
RECOMMENDED SURVEY QUESTION (Q) AND POSSIBLE ANSWERS (A)
Q1: Do you sell [specify the product]?
A1: yes / no
(ask the following question only if the previous response is YES)
Q2: Can I please see the [specify the product]?
1) product is available
2) product is normally available but is currently out of stock and will be available soon
3) product was not available and it is not clear when it will be sold again
To calculate the indicator's value, sum up the number of sellers offering the given product (or are waiting for the product to be restocked within a short period).
