I hate to ruin your day, but Christmas day is just 20 days away. That’s right, in a little less than three weeks from now you’ll be expected to have bought presents for friends and loved ones, as well as the Christmas turkey and all its trimmings. If like me, you have soothed yourself with the mantra of “No need to worry, it’s next month“, it’s now time to get moving. While you can buy pretty much everything from Amazon, something to keep in mind, even if you have Prime, is that the online retailers’ delivery times tend to slip a little at this time of year. With this in mind, Amazon has launched a handy little Holiday Delivery Calendar to help you time things to perfection.
