All the tools in this country are imports now (well virtually all), and around 60% of what I'm planning to sell is £10 or under, so hopefully pretty good value?
Personally, I think you need to go to the next level of tool at a minimum. Step up to something like a Tektron or Sunnex or Astro or Toptul or Gearwrench.
Its not so much about being cheap as being value. Sunnex are "cheapish" but very good tools, therefore good value. Same as Gearwrech and Astro's offerings.
I know I wouldnt buy those tools even at $20, even if delivered to my door. Its not about being a tool snob (im not, I have lots of GW, Sunnex and rebranded Astro), but those tools you are carrying are the tools you see in the bargin bin at the dollar store! I dont mean that as insulting, just those types of tools dont last in service (for me). And even as cheap as they are, guys WILL be expecting you to warranty them as a dealer. Youre heading for a major headache, low grade tools and having to warranty.
I guess what Im saying is for me, I wouldnt even consider buying less than GW/Sunnex/astro/Toptul (AKA the Taiwan brands) as a tool I can rely on.
Id also add Wera as an "upper mid level" brand. Maybe Knipex for what they offer in pliers. Or even Beta or Facom. Both are solid upper end Euro tool brands not sold much in NA.
We had a guy local who did something similar to what youre doing minus the consumables. He carried SK as his main line with Sunnex and GW as a secondary. He was independent but basically acted as a mobile store for a
wholesaler out of Quebec named G2S.. He stocked the standard stuff and would order whatever else you needed delivered for the following week. He also gave out their flyers.
Dont underestimate your overhead. Youre in an expensive area like I am, fuel and insurance are crazy. That guy above had to close his semi-rural route back home and move to the city to make enough money!
Another thing to consider diversifying into is bolts and fasteners.
