ILLUSTRATIVE COMPARISON — FICTIONAL USD PRICES, BEFORE TAX Required blocks: 178. Required caps: 26. Supplier A: 178 blocks × $2.75 + 26 caps × $4.50 + $75 delivery = $681.50. Supplier B: 3 full 75-unit pallets (225 blocks) × $2.60 + 26 caps × $4.50 + $60 delivery = $762.00. Supplier B provides 47 extra blocks and costs $80.50 more for these lines. This comparison excludes aggregate, pipe, fabric, adhesive, labor and other project costs. Replace all prices with your own quotes.
