Jomashop takes up to 71% off a selection Rado men's and women's watches for its Rado Doorbuster Sale. Plus, take an extra $10 off via coupon code "DNEWSFS10". Even better, all orders receive free shipping. Deal ends December 14. A couple of best bets, with prices after coupon:
Rado Women's DiaMaster Automatic Watch for $649.99 (low by $43)
Rado Men's D-Star Black Dial Automatic Watch for $685 (pictured, low by $45)
Making even one of these mistakes can easily cost you tens of thousands of dollars.
