A question about retail buyers and items on sale.

[Workingmytickettoparadise]

Do retail buyers analyse what items end up in the sale and make future buying decisions based on the data?

Not a buyer, but I'd say yes to an extent, depends on the shop. I imagine big stores have already designed or bought a lot of their AW ranges. But obviously it's good business sense to sell as much as possible at full price.

I worked in Buying and Merchandising for many years and the teams do a great deal of analysis when buying future ranges. They look at how quickly lines sold and what is cost (if anything) to reduce the selling price to liquidate the line.
Every week they review best and worst selling lines and take action - buy more through to promote or reduce selling price.
Some products have long lead times (from fabric, to production, shipping and delivery to store/distribution centre. Changes can't be made easily once production starts so you can be stuck with lines which can't be amended if lead times are long.
