spave
v.— «My oldest daughter’s friend Polly calls bargain hunting “spaving,” which she defines as “spending to save… because while you are spending money, you’re actually saving on the full price.” I like the word and even the thought behind it, but even Polly had to admit that she’d rather “spave” her money buying soda and candy—something she’ll use—than a case of motor oil, which she won’t.» —“Buying ‘bargains’ can be expensive” by Chuck Jaffe in Boston MarketWatch Feb. 2, 2005.
