Request for the Purchase of 'Sony' Networking Switch

The networking switch used in xxx Branch is malfunctioning and needs to be replaced.

We wish to recommend that the item be purchased from GRP, which are one of our regular IT suppliers and are the sole distributor for SONY products. We attach here a quotation from GRP for the item for your information. We look forward to your approval.

You have to get the item from them if they are the sole distributor, not just an authorized dealer. There could be other authorized dealers, in which case, price would be the deciding factor.

Only this company sell such switch non of them sell here in KWT.. you are correct having maintenance contract with them isn't a good reason
