Janet E. Levy's perception of the Giant and Safeway campaigns that offer computers to local schools in exchange for cash-register receipts was on the mark -- students in low-income neighborhoods are the least likely to benefit {"At the Checkout, Means to Make a Difference," Close to Home, Nov. 4}.

In the Giant project, nearly 50 schools collected in excess of $1 million each in receipts. All the schools were in the suburbs, though -- not one in the District. Similarly skewed results probably occurred in Safeway's computer program.

Neither food chain acceded to a request last year to modify its programs to help low-income area schools in the District, Virginia and Maryland. Maybe Giant and Safeway will reconsider their policies, but meanwhile other ways do exist to ameliorate this problem.

Secular and religious groups are a good source of aid, as Levy mentioned. But another logical place to turn is to the suburban schools in the $1 million class. Students at these prosperous schools could sponsor a school in a low-income area by donating, say, 10 percent of the value of their accumulated register tapes. That would be a wonderful opportunity to share their resources and good fortune with schools that try daily to cope with overwhelming problems.

On Capitol Hill, we have taken Janet E. Levy's suggestion to heart and shared the wealth.

With the help of a grant from our local business association and the leadership of a local private school, we have employees of 100 local businesses accumulating Safeway and Giant sales slips for the benefit of public, private and parochial elementary schools on Capitol Hill. In this way, the non-parent neighbors and commuters can participate in helping our children's education.

Merchants have given counter space, volunteers have been plentiful and thousands of dollars in sales slips have already been placed in our hands by people who took the time to save and deposit their slips in the boxes all over Capitol Hill.

Cooperative efforts by parents and administrators in conjunction with private enterprise can go miles toward supporting our schools at a time of reduced taxpayer ability to support such programs, rising private and parochial school tuitions and increased reluctance by local governments to fund anything more than the basics.

The disparity between the suburbs and city, as noted by Levy, is played out within our neighborhoods as well. But here on Capitol Hill, we have recognized our differences and our sameness and have taken responsibility for bridging the gap in the community we live in.

For those citizens without school association or school allegiance, the accumulated receipts from Safeway and Giant stores are more than a drop in the box -- they represent the future of an entire generation in our neighborhood.
