Sales comes from a genuine need. Your perspective clearly indicates you think this is product pushing - and value added sales isn't product pushing. If your customer needs an external hard drive RAID array for backups of mission critical data, would benefit from a hosted solution, or would obtain other value from a software upgrade, SELL IT. Your salary doesn't fall from the sky. It takes a team of people bringing customers in and generating revenue to pay you. You should share in the challenge of keeping the enterprise afloat if you expect to be compensated for what you do.
