Thanks to those who suggested using the Voronoi tool. With a bit of messing around i have been able to figure out a way to create buffers, using the Voronoi tool, which do not overlap. It's a bit tricky but i'll try to explain it as best i can.
I created 2 new layers, which i simply called VORONOI and BUFFER. Firstly, i had to create 4 extra points, one on each side (north, south, east and west)of my actual store locations. The point of this is to create a VORONOI box large enough to cover the areas AROUND all my store locations, not just IN BETWEEN my store locations. (i needed voronoi polygons large enough to cut my buffers without cutting "other" bits off my buffers that i wanted to keep) Selecting all the points, i created a voronoi onto my VORONOI table. Then i deleted the voronois associated with the 4 dummy points. Next, I created the buffers onto my BUFFER table. ...this is where it gets a bit finnicky. by selecting one BUFFER, and then selecting the VORONOI polygons associated with the OTHER stores, i deleted the parts of the buffer which would overlap on other buffers. doing this for each store, I deleted the offending overlaps and have ended up with buffers for each store which do not overlap. Note: i had to keep swapping my BUFFER and VORONOI tables on my layer control to allow me to select the buffer i wanted to edit (set target) and then place the voronoi table over the top again to select the voronoi polygons. -Time consuming, Yes, but not as bad as using the old Polyline split/delete/mess around routine and more accurate. I sincerely hope this explanation makes sense. If anyone needs it explained better, drop me an email and i'll try. Cheers all for your help!

See attached file: I would have thought there'd be a function that builds buffers like this, 'cause surely I'm not the only one who needs to buffer objects and have the buffers meet but not overlap???
