Here are 5 things you should know.
1. If you’re job hunting, mention it to everybody that you can.
You never know whose brother’s neighbor’s dog-sitter is hiring.
2. Credit cards with contactless payments have cumulative spending limits that are reset when you pay using your PIN.
If you are seeing proximity transactions refused despite having available credit, you have probably reached the limit.
Try the transaction again using the chip card and your PIN, the limit will be reset and contactless payments will begin working properly again.
If you regularly use your PIN, you will probably never hit the limit.
3. Diamonds are of no use.
Their prevalence as engagement rings is only because of a very very successful marketing scheme: https://priceonomics.com/post/45768546804/diamonds-are-Bulls**t
4. As a reminder, the IRS does not call your house and does not send emails if there is a problem.
- Call to demand immediate payment, nor will the agency call about taxes owed without first having mailed you a bill.
- Demand that you pay taxes without giving you the opportunity to question or appeal the amount they say you owe.
- Require you to use a specific payment method for your taxes, such as a prepaid debit card.
- Ask for credit or debit card numbers over the phone.
- Threaten to bring in local police or other law-enforcement groups to have you arrested for not paying.

5. EpiPen is a brand name, but if your doctor writes a script for “epinephrine auto-injector” you can get cheaper and just as effective alternative pens.

Of note, there are now generics available with the EpiPen mechanism, but you can’t get brand alternatives if your doctor writes for EpiPen because the pens have slightly different mechanisms, and as such are not considered substitutable by pharmacies. For example, some alternatives require you press the pen to the body for ten seconds instead of three seconds. They are just as effective medically but are slightly different. This could save you hundreds of dollars.
Also on #4, banks and other financial companies do not text you with links to fix your “Frozen” account or call you without identifying themselves and your account information. Never give out passwords or credit card info or answers to verification questions on calls or texts purporting to be from your bank or credit card company. Hang up and either log in online or call them at a known number to check and see if there is an actual problem first. I’ve gotten scam calls and emails lately, they seem to be going around.
Diamonds are used in drill bits for mining. I would say they are of tremendous use.
