A hint to the wise: Load up on everything you may think you needfor Easter Sunday, because come that day, going to the store to pick up whatever you seek or crave, may be impossible.

According to SavingAdvice.com, here in the U.S. it's a crapshoot as to what stores, restaurants and other venues plan to open their doors on Sunday. For example, the website notes that Walmart will be open, while such rivals as Target and Costco plan to remain shuttured for the day.

While most grocery stores and even drug stores plan to open for the day, according to SavingAdvice.com, such certainty isn't nearly as ironclad when it comes to restaurants.

"It varies," the website notes, adding that "there is no set standard on whether a restaurant will be open or not. If you plan to go out to eat on Easter, your best bet is to call the restaurant ahead of time to make sure they will be open, and what their opening hours will be."

As for grocers, most of the larger national chains, such as Safeway and Kroger, are expected to be open, though it's uncertain if their normal business hours will be in anyway altered. All Publix outlets, on the other hand, will be closed.

All banks, credit unions and post offices will be closed, even TD Bank, which is typically open for business on Sundays. All those facilities will resume normal operations on Monday.

Meanwhile, ATMs and online website for banking institutions will remain functional and operational on the holiday and many banking transactions can still be performed through those channels fr those using online services.

Most, but not all, gas stations are expected to be open and will keep normal business hours.

The world's largest retailer, in recent times Walmart has seemingly engaged in a change of strategy to offset a tough and stagnated economy. According to CNBC.com, company execs recently announced a plan to open more small stores and combine them to some of their supercenter outlets.
