Sometimes, the suppliers, quantity, rent, wages, loan payment or liquid cash or credit limits, required markup percentage, and if ad'd offered droping the profit margin, can make a big difference in the outcome of the asking price. Probibly way more than you wanted to know :)
Have always been told: profit, volume, controlled expences can be sucessful with 2 of the 3 but not just 1.
No matter good luck to them both.
