Solver Paints

What people can't paint on Sundays according to Solver i.e they're shut ! Hmmm makes me grumpy.

My gripe with Solver is the quantities in which they package their paint. Wishing to paint an interior wall I calculated that I would need approx 1.5 litres of paint based on their recommended coverage guidelines. But you can not buy a 2 litre tin of paint, they advised that I can buy 1 litre at $33 or 4 litre at $65, why the big jump and why the large difference in price, this would suggest the tin and the service is worth more than then the paint. Now I am stuck with another tin of left over paint that will sit in the garage for years....come on guys look at customer needs, not up-selling paint that we don't need.
