This example uses FDELETE to delete an empty directory to which you have write access. If the directory is not empty, the optional SYSMSG function returns an error message stating that SAS is unable to delete the file.
Costcoâs business model is called a subscription business model â customers who want to shop at the store must buy a membership (currently $55 in the U.S.) with the promise of lower prices to make up for the initial upfront cost.
The price of a subscription varies depending on what you get per month. $14.95 for one book and one month's subscription to e.g. an NPR program; $21.95 for two books. That's it.here's some throwing around of 30% and 80% discounts, but that's just what you already see -- the ~$15 or ~$22 of your subscription, managed correctly, can get you about five times as much in list price value; and the things you buy from the catalogue are going to be about 30% off.
