For its members, Costco offers the Khombu Men's River Sandals in Black or Brown for $4.97 with free shipping. (Non-members pay a 25-cent surcharge.) That's a very low price for men's sandals, especially Khombu brand. (For further comparison, used pairs start at around $10 before shipping on eBay.) They come in select sizes from 9 to 13.
Most taxpayers will see their tax bill go down during 2018. That could impact which type of account -- traditional or Roth -- makes sense for you.
