Have 2 here just 11 months. Have spent hundreds in advertising them. If they don't move in the next 6 weeks there off to a friend in the trade. Thankfully it doesn't happen too often, but it happens.
2 months is nothing especially this time of year.
Having more stock would mean the phone is always going and something is always selling. Thus you're less likely to get depressed or wonder if the world is going to end
