My regular readers know that I can pinch a penny until it squeals—and there’s nothing I like better than to share a bargain. This one is a doozy, with blast-from-the-past pricing: a full manicure and pedicure, just $22 on Mondays through Wednesdays at Ivy Nails (15 N Central Ave, Hartsdale, 914-946-6245). Owners Betty Choi and Joanne Lee, who opened the salon last month, have kept their regular prices on Thursdays through Sundays reasonable, too: just $9 for a basic manicure, $18 for a pedicure; with add-ons like a callus removal treatment for $10 (so worth it) or a 10-minute reflexology massage for $13. The little ones can accompany Mom; kid manicures range from $5 to $7; pedicures $10 to $14. The salon also has a full menu of wraps and extensions, plus waxing. Parking is free, just behind Duane Read.
