Tractor Supply (NASDAQ: TSCO) is one of the primary beneficiaries. The rural-lifestyle retailer just reported blowout third-quarter earnings. Although its 10-year track record of reporting double-digit e-commerce sales growth was broken earlier this fiscal year, online sales continue to expand and remain a key component of Tractor Supply's long-term strategy to reach new markets and customers. It took Tractor Supply 72 years to open 1,000 stores, then just 10 years to open its next 1,000 locations.
