Compensating fancyness

I know, I know, packaging is super important to make the sale . But when they already purchased my drill bit holder online – it is in fact already sold.

Lowest shipping cost
To post my invention I use an extremely light weight plastic envelope that looks like crap. However, if someone orders just one Gearfix I can post it to every corner of the world at the same price as an ordinary post card.
Tipping the scales
If someone buys two or more drill bit holders online the shipping cost doesn’t change. And for larger orders, when it doesn’t affect my shipping expenses, I some times add a bonus Gearfix just for fun.
Compensation
The cheap plastic envelope is the opposite of fancy. In case any customer happens to get offended by the packaging I imagine filling it with an unexpected bonus product will take their mind off the crappy container.
