"Spend" as a noun?!

[Wilson Gray]

While leafing through a mag called _ComputerWord for Pharmacists_, I ran
across the phrase, "... would entail a greater *spend*." A quick look at
Google yielded 206,000,000 hits, clearly too many to sift through, for
"spend." However, "greater spend" yielded a more manageable 712 hits,
including, e.g. ",,, ensuring greater _spend_ per visitor ...," "Fewer
stops. Greater _spend_," and "... the greater spend of foreign visitors."
