If your thoughts turn to love and romance on Valentine’s Day, be prepared to pay more for it. LPL Financial tracked the cost of four typical Valentine’s Day gift categories and found evidence of inflation. According to LPL’s Valentine’s Day Index, the prices of those gifts increased by 1.3%, which is faster than the overall rate of inflation. ‘Dinner and a movie is probably one of the few items that has consistently posted price gains,’ said Anthony Valeri, Investment Strategist at LPL Financial. ‘That increase is up over 3%. Going out on the town is definitely the most expensive item in terms of year over year price gains.’ LPL includes the cost of a babysitter in calculating expenses for a night out. A better bet is to stay home. LPL priced the costs of a night in using four common gifts: candy, flowers, a home cooked dinner, and a bottle of bubbly or wine. The cost for staying home rose just slightly in 2015, mainly due to higher food costs. There’s good news for big ticket spenders, as jewelry prices have fallen.
