It's that time of the year again when retailers wave perks and promos in your face to earn your business. Walmart is hoping to lure you away from Amazon by offering free two-day shipping for millions more items sold by third-party Marketplace sellers on top of the ones it's selling directly. The retailer has teamed up with hundreds of top-selling third-party merchants to expand its free shipping offer for purchases worth $35 and above. You don't need to pay a membership fee to take advantage of it, the company kept stressing in its announcement, perhaps in an effort to remind you that Amazon Prime now costs $119 a year in the US.
