Phil's Army Surplus calculator business was going great guns -- especially the newest models with exclusive camouflage color schemes. Phil sold the calculators from his own dedicated web site: Phil-the-bill.com and had consistent sales of 630 units per week. The calculators sold for $40 earning Phil a margin of 44% percent. He also sold the calculators for the same price through an online department store, BigMuddy.com. BigMuddy earns a 19% commission on sales resulting from clickthroughs originating from BigMuddy. The latter accounts for 10% of total unit sales and somewhat less of dollar sales after commissions were paid.
