Who is a Jews? Court Ruling in Britain Raises Question

I once asked my Israeli colleague, is Jewish a religion or a race, as a Jew himself, he doesn’t know the answer. If a Chinese school admits only Chinese students, I am sure it will sued by the government. However, it is OK for a Christian school admits only Christian students. In the sense a Jewish school should refer to Jewish as a religion but not Jewish as a race.

How much does the iPhone really cost in Canada?

Nothing beats my wife’s iPhone plan with Fido. $17 per month with unlimited voice on evening and weekend, standard voice mail, calling forwarding, call display, text messages package. The catch? No data plan. Call Fido to disable data service so the iPhone will not use any data accidentally. Having Wifi for data connection is good enough.

Extended price guarantee

Many big chain stores in Canada has price guarantee. If something you had purchased is on sales in the next two weeks, you take can get price difference with receipt. Don’t be fooled by the two weeks only price guarantee period and thought you can’t get your money back after two weeks. Most stores also has a 90 days refund period. If the item is on sales in the next 90 days, you can always refund any unused, unopened item in original box with receipt.

Now You may ask how can you refund something if it is already opened, used and even threw away the box. Here is the trick. Most important of all, always keep your receipts. First bring your old receipt to the shop, then buy a new item that’s on sales. Make sure the bar code of the new item is the same as the one on your old receipt. Walk to the customer service straight from the cashier and refund the newly bought item with the old receipt. As long as the bar code is the same, the shop has no way to tell whether you bought the item 89 seconds or 89 days ago. If your screwed up and the bar code is indeed changed. Don’t worry, you can always refund the extra item with the new receipt.

In fact you can use this method to extend the price guarantee period indefinitely. Repeat the above steps right before the 90 days refund period expire to extend the refund period by another 90 days. As long as you remember to check the flyers every week, you can get your money back until they eventually discontinue the item or change the bar code. As long as the bar code is the same, you can even refund an newly bought item from one shop with an old receipt to another shop.

Can high school grades be trusted?

Credit shopping is nothing new. I did it when I was in high school many many years ago. I took my English OAC in a public school in summer because the English teacher in my school is really though. Buying the credit without studying is a bit too much, but it is natural that students will take the difficult courses with an easy teacher. For example, I got a 20% grade increase. That makes a huge difference in university application. The only fair admission system is public exam system like HKCEE.
