To date, the album has sold more than 350,000 copies, 137,000 of which were US sales and around 17,000 of which were sold in the UK, making this their lowest-selling official release. Despite this, the lead single "Penny & Me" achieved some success, reaching #2 on the Hot 100 Singles Sales chart and #10 on the UK Top 40. The second single, "Lost Without Each Other", did not chart in most countries, and only reached number #39 on the UK Top 40. Hanson themselves have said that they endured a financial loss in making and releasing the album, to the point where in some places, the album itself transitioned from mainstream retail locations to discount stores, particularly across England. It has been speculated that any loss endured has been made up from tour proceeds, as they tend to generate more direct income for bands than record sales can.
