well as favorable mix, drove the increase in price/mix. The ongoing recovery in demand at full-service restaurants and in non-commercial channels (such as lodging and hospitality, healthcare, schools and universities, sports and entertainment, and workplace environments) drove the increase in sales volumes. While shipments to restaurants have essentially returned to pre-pandemic levels, demand in non-commercial channels remain below pre-pandemic levels. The segment’s overall volume growth was tempered by softer restaurant and non-commercial traffic as a result of the effects of the Omicron variant, as well as our inability to fully serve customer demand due to widespread industry supply chain constraints that resulted in lower production run-rates and throughput in our factories.
Retail segment net sales declined $18.9 million, or 12%, to $143.6 million. Volume declined 24% while price/mix increased 12%. Lower shipments of private label products, resulting from incremental losses of certain low-margin business, as well as lower shipments of branded products drove the sales volume decline. The decline in branded product shipments reflected our inability to fully serve customer demand due to widespread industry supply chain constraints that resulted in lower production run-rates and throughput in our factories. Product and freight pricing actions across our branded and private label portfolios to offset inflation, as well as improved mix, drove the increase in price/mix.
Net sales in our Other segment declined $6.3 million, or 18%, to $29.0 million. Volume declined 20% and price/mix increased 2%. The decline was driven by lower volume in our vegetable business, reflecting the negative effect of the extreme summer heat on the yield and quality of the vegetable crops.
Gross Profit and Product Contribution Margin
Gross profit increased $24.3 million, or 12%, to $221.0 million, as the benefits from higher price/mix more than offset the impact of higher manufacturing and distribution costs on a per-pound basis, as well as lower sales volumes. The higher costs per pound primarily reflected double-digit cost inflation from key inputs, particularly raw materials such as edible oils, ingredients such as grains and starches used in product coatings, and raw potatoes, as well as higher transportation, packaging, and labor costs. The increase in costs per pound also reflected the effect of labor shortages on production run-rates, as well as lower raw potato utilization rates related to the poor crop harvested in fall 2021. The increase in per pound costs was partially offset by supply chain productivity savings. The increase in gross profit also included a $1.7 million increase in unrealized mark-to-market adjustments associated with commodity hedging contracts, which includes a $3.6 million gain in the third quarter, compared with a $1.9 million gain related to these items in the prior year quarter.
Lamb Weston’s overall product contribution margin, defined as gross profit less A&P expenses, increased $26.2 million, or 14%, to $217.5 million. The increase was largely due to higher gross profit (as described above) and a $1.9 million decrease in A&P expenses.
Global segment product contribution margin declined $6.3 million, or 8%, to $73.0 million. Higher manufacturing and distribution costs per pound, as well as lower sales volumes due to limited shipping container availability, more than offset the benefit of favorable price/mix. Global segment cost of sales was $413.9 million, up 4% compared to the third quarter of fiscal 2021, primarily due to higher manufacturing and distribution costs, partially offset by lower sales volumes.
Foodservice segment product contribution margin increased $36.5 million, or 52%, to $106.7 million. Favorable price, volume and mix drove the increase, and were partially offset by higher manufacturing and distribution costs per pound. Foodservice segment cost of sales was $186.7 million, up 26% compared to the third quarter of fiscal 2021, primarily due to higher sales volumes and higher manufacturing and distribution costs.
Retail segment product contribution margin declined $1.5 million, or 5%, to $31.6 million. Lower sales volumes and higher manufacturing and distribution costs per pound drove the decline, partially offset by favorable price/mix and a $1.6 million decrease in A&P expenses. Retail segment cost of sales was $110.6 million, a 13% decline compared to the third quarter of fiscal 2021, primarily due to higher manufacturing and distribution costs, partially offset by lower sales volumes.
Other segment product contribution margin declined $2.5 million to $6.2 million in the third quarter of fiscal 2022, as compared to $8.7 million in the third quarter of fiscal 2021. These amounts include a $2.8 million gain related to
