USB Chargers
Are you planning to buy cheap chargers which do not give devices the TLC they need? If so, go to the dollar store and buy USB chargers! You will likely be disappointed if a full charge was what you wanted for your smartphones and tablets. There isn’t enough juice in those chargers for your devices or they will charge them much more slowly.
HDMI Cables
Fair enough, a lot of places sell HDMI cables at indecent prices, so it is not surprising to hear that a lot of people are tempted to go to the dollar store instead to save money. While these cables are indeed much cheaper, they are actually more likely to break. It is better to get HDMI cables from online stores. You can find good deals online if you just go look for them!
