For standard large (approx. 4.5 cubic feet) and extra-large moving boxes, major retailers offer competitive pricing and varied strengths:
: Generally has the lowest per-unit price (sometimes as low as ~$1.00 - $2.26) but may use thinner cardboard that is less durable for long-distance moves.
: Best for budget-conscious bulk moves. Their XL boxes are often cited as the most cost-effective for their size, and they offer higher Edge Crush Test (ECT) ratings (up to 48) for heavy-duty needs.
