Let the games begin: Retail places holiday wagers · CNBC

With incomes on the rise, more jobs being filled and shopper confidence trending higher, it seems like a pretty safe bet that retailers will benefit from a stronger consumer during the winter holidays.

But as evidenced by the turmoil in Greece this week, there are still plenty of unknowns that could cause consumers to snap shut their wallets, leaving retailers with excess inventory, and resulting in another year of price slashing.

Though the Greek debt woes feel a world away to many U.S. consumers, the ongoing crisis caused stocks to log their worst day of the year on Monday, and broke a nine-quarter streak of S&P 500 quarterly gains . It also has prompted speculation that the Federal Reserve could change the timing of an expected interest rate hike .

Such ripple effects could result in more uncertainty for U.S. shoppers as time goes on. A deeper, more prolonged drop in the stock market, for example, could cause high-end consumers to reign in their spending.

Experts said that retailers' performance over the back-to-school shopping period-the second-largest selling season-should give retailers a better sense of what's to come later this year.

"A lot of them are looking to back-to-school as the final test of what they can do to lay out their holiday strategies," said Steve Barr, U.S. retail and consumer sector leader at PwC. "It's going to be a really important indicator."

Although retailers have adopted a wait-and-see attitude, many expect to see a bounce back in the second half, said Rod Sides, U.S. consulting leader for retail and distribution at Deloitte. As such, he predicted that "a lot of them are going to be fairly aggressive" with their orders, most of which have already been placed.

Sides added there will also be a greater emphasis this holiday on the allocation of inventory, as retailers look to boost their margins by storing their merchandise in the most profitable locations. This has become increasingly important as bricks-and-mortar stores are filling more of their orders from their local shops, including the option to ship from or pick up online orders in store.

More retailers are also tapping into the read and react capabilities used by fast-fashion retailers such as H&M (Stockholmsborsen: HM.B-SE) and Forever 21, made possible by a more streamlined the supply chain. This allows companies to place smaller bets on their initial orders, and then replenish their stores with the best-selling products.
