It’s the quintessential under-the-Christmas-tree gift: a shiny red tricycle. And it just got even more affordable. I spotted this Radio Flyer Classic Red Dual Deck Tricycle at Amazon.com for just $48.54 (regularly $89.99), plus it ships free in 2 days with Amazon Prime (if you haven’t joined Amazon Prime yet, what on Earth have you been waiting for???). The trike has a faithfully-executed retro design, right down to the smallest details- a chrome front fender, red-and-white tassels on the rubber-coated handlebars, and even an old-fashioned bell. Now, if you’d prefer it in pink for a little girl (not that there’s anything wrong with that), the pink version is also a steal at $47.38. Go ahead, make a little kid’s holiday. And check out Amazon’s other big-time Radio Flyer bargains (but hurry, the bargain prices tend to disappear without notice).
