根据短文内容,从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余选项。

     Shoppers who carefully plan their visit to the grocery store  can save money on their grocery bills.

__1__

     Shoppers should visit the grocery store on a full stomach  by scheduling their trip immediately after a

large meal. If that's not possible, they should find something healthy to eat while preparing a grocery list.

  __2__

     Although having a list and sticking to it is the most important factor in saving money, shoppers must

prepare lists wisely in order to save.   _3_ Many special buys are announced  through the local

newspapers, so buying the "grocery issue" is  worth the investment(投资). However, it's important to

remember that many newer, more expensive products first offered  through coupons(优惠券) may not

yield enough savings for shoppers to  give up the product they usually buy.

     _4__ Once at the store, the shopper who wants to save  money should follow a few more rules. The

shopper should not stay longer than necessary, because bills go up each minute the shopper is in the store. So, setting a time limit and a cost limit can hold down the bill.   __5_  If the grocery list is a short one,

some shoppers choose to use the small handheld basket instead of the roomy grocery cart.

A. A carefully planned list should include in season produce and any items on sale or discounted through

coupons.

B. Of course, the shopper should stick strictly to the shopping list and resist the temptation to buy

additional items.

C. People who are full are less tired and more likely to buy what they want.

D. Now that the shopper has completed the grocery list, it's time to leave for the store.

E. You should keep your shopping list carefully in case you can exchange it for coupons.

F. Most shoppers are less persuaded to buy extra goods when they are not hungry.

G. Shopping when not hungry, sticking to a grocery list, and following a few simple rules will

     cut down the grocery bill.
