18. Scour Groupon for travel deals.
“My husband and I took a trip to Thailand through Groupon that was over 35% cheaper than it would’ve been otherwise. One package included airfare from SFO to Bangkok, one flight to Phuket, and one flight back to SFO. It also included a tour guide who provided transportation to all of our stops, free breakfast for the entire trip, and to top it off, the exchange rate is 34 baht to the American dollar. Best trip of our lives!”
