Hi
I would use a pivot table for this. see:

I am looking to add up all Values in Column E (quantities of products
sold) for each product by store.

The effect of this is that all Products that are the same (which are
in Column C) that relate to the same store (which are detailed in
Column A) are totalled up. I then wish to delete these rows (that
have been added and are thus no longer needed) - something likea
subtotal except I only want the 'subtotal' rows

One way I thought I could do it might be add when A2=A3 AND OR C2 =
C3, these would continue progressing down my worksheet until A2 does
not equal A3 i.e. new Store and C2 does not equal C3 i.e. new product

Hope that make sense

Thanks
