*lets suppose....
Soho Airways has a ticket at list price £1,000.
They put on a Summer Sale promotion, cutting the price to £955
Or, they credit the customer account with £45 to use against future business.
Or, they repay a cash rebate of £45
Who is the customer?
Who does the £45 belong to?*
There are 2 issues I can see here:
Using a more expensive website to get a benefit, which is what is classically called a kickback- this is clearly corrupt and wrong.
Or:
Using a cash back website to purchase the same thing you were going to purchase anyway, at the same price. I can buy a box of widgets for £10 from Tesco or Sainsbury’s. Having a nectar card, I choose sainsbury’s.
Now- if my boss has said “go to Sainsbury’s and buy a box of widgets and here’s my nectar card” then yes, it’s his prerogative- after all you’re spending his money.
But if he doesn’t care and the company doesn’t have a nectar card, what is immoral about using your own?
