Back in the real world of things, I ran an experiment recently with t-shirts, and created a 'Premium' design to sit alongside my existing design which I renamed 'Classic'.
The new tees were priced at £35 instead of £25, and I was expecting them to increase sales of the Classic tees, but actually the Premium tees sold waaaaaaay faster.
