Okay - well 3 things here...
#1 - Now go back to your boss with 6x4 prints of all of these and suggest to him that (for a slight payrise) he could have these ENLARGED and use them at the store-front as advertisements...
#2 - (assuming that SuperSaver is national, and has and distributes a letterbox flyer of their produce on sale) ask your boss to nominate your photos to head office for inclusion in the flyer... (Head Office will be paying some other photographer to take pics.. so why not YOU..?)
#3- I'm in Australia, previously a Brit (but I'm alright now)... In Pic 3, what are the squat-looking peaches called? - I never saw a peach that shape before... usually, they're sorta round...
