If you want to give a holiday surprise to a technology geek in your life, consider giving a simple gift card. It may seem lazy or low-effort, but they will undoubtedly find use in it via stores like Newegg or Amazon. Just be careful with gift cards for specific music services (like iTunes) or gaming gift cards for platforms they don't play on (get a Playstation gift card if they use a PS4).
Adam wants to build a PC. Should he get stuff during Black Friday or Cyber Monday? Leo says he doesn't recommend building computers anymore because he can get it cheaper from a company like Dell, and he'll get at least some support for it. It's a great project though. But he'll have to be his own support.
Leo recommends calling NewEgg to find out about their price matching policy, so if he buys something now and it's cheaper on Black Friday, he'll get back the difference.
Alem and a friend in the US have created a product they want to sell online. Leo says that shipping to other countries will involve tariffs and taxes. So it's important to fulfill in country. Leo says that Amazon does fullfillment and they specialize on small businesses and can handle overseas shipping as well. If it's a tech product, there's also NewEgg. Both handle fullfillment for small businesses.
