Despite holiday shoppers’ lists and budgets, a recent survey by the National Retail Federation found that 40 percent of consumers spent at least $50 more than they originally planned during the 2015 holidays. One in eight shoppers went $200 (or more) over budget.

Five reasons shoppers said might convince them to go beyond their gift-buying budget by $25

51% | A really good sale or promotion

34% | Seeing  a perfect gift for someone not originally on the gift list

27% | Finding something perfect for self

17% | Needing additional items for last-minute parties

27% | Free shipping with no minimum threshold

Good deals

This is why you are seeing deals and discounts touted far and wide — and will through the end of the year.

Irresistible products

Millennials, who are now solidly into adulthood, are more likely than their older counterparts to spend more in this situation

Me-gifting

One-quarter of consumers admit they could be swayed to spend more money just by seeing something fabulous for themselves.

Party panic

Retailers have been implementing new strategies for consumers to get what they need quickly.

Convenience

Sometimes consumers just need a little something extra to get them to spend more. Free shipping that doesn’t require a minimum threshold is one of those things. Shoppers can be convinced to spend more if they were being helped by knowledgeable and friendly salesperson could convince them to buy something that’s not on their list.
