I have a trade account with Trade Depot, 5% off. Need it by Friday. Dunmore said battens restock next Wednesday.

AFTER · what the skill produced

Summary: We recommend buying everything from Trade Depot for 501.50 before tax. It is one delivery, it covers the full quantity by Friday, and it is the lowest total of any option that can deliver everything on time. Splitting the order across suppliers would save a few pounds on some lines but cost more in extra delivery. None of the quotes had a validity date, so please confirm prices before ordering.

Line-by-line (hinges: 4 sets = 4 pairs, as you wrote "4 sets of 3 inch door hinges (pairs)". Please confirm.)

| Item | Qty | Trade Depot | Harlow | Dunmore |
|---|---|---|---|---|
| Sanitary silicone | 12 | 6.40 = 76.80 | 5.90 = 70.80 | 6.10 = 73.20 |
| Ready mixed filler 20L | 6 | 28.00 = 168.00 | 31.50 = 189.00 | 29.00 = 174.00 |
| 3 inch hinges, pair | 4 | 9.50 = 38.00 | 8.25 = 33.00 | 10.00 = 40.00 |
| LED batten 4ft | 10 | 18.75 = 187.50 | 21.00 = 210.00 | 17.50 = 175.00 (only 6 in stock now) |
| Sanding sheets, pack | 8 | 7.20 = 57.60 | 6.80 = 54.40 | 6.50 = 52.00 |

Totals per supplier

Trade Depot: items 527.90. 5% account discount is 26.40 (26.395 rounded), so 501.50. Delivery is free over 300. Total 501.50.
Harlow: items 557.20. Delivery 20.00. Total 577.20.
Dunmore: items 514.20. Delivery is free over 250. Total 514.20, but only 6 of the 10 battens are available by Friday.

Best mix (cheapest per line, discount included)
Trade Depot prices after the 5% discount are: silicone 6.08, filler 26.60, hinges 9.025 (9.03 rounded), battens 17.81 (17.8125), sanding 6.84. On that basis Trade Depot is cheapest for filler. Harlow is cheapest on silicone and hinges. Dunmore is cheapest on sanding, and also on battens (17.50 against 17.81). However, Dunmore cannot supply all 10 battens by Friday, so the battens stay with Trade Depot because of the stock limit, not the price.
Moving silicone and hinges to Harlow and sanding to Dunmore would mean three deliveries. Harlow's part would be 103.80, under any free delivery level you gave us, so it adds 20.00 delivery. Dunmore's part would be 52.00, under its 250 free level, so it adds 30.00 delivery. The savings against Trade Depot after discount are:

Silicone: 72.96 minus 70.80 = 2.16
Hinges: 36.10 minus 33.00 = 3.10
Sanding: 54.72 minus 52.00 = 2.72
Total possible saving is 7.98, which is far less than the 50.00 in extra delivery. Splitting does not pay, so the best mix is simply Trade Depot for everything at 501.50.

Notes

Dunmore battens are cheaper but only 6 are in stock, and the restock is next Wednesday, after your Friday deadline. Dunmore cannot cover the full order in time.
We could not confirm that the silicone, filler and battens are the same brand or spec across suppliers. Please check before ordering.
Trade Depot has the account discount and free delivery, so it is the simplest option and the cheapest that can deliver everything by Friday.

Recommendation
We recommend ordering everything from Trade Depot for 501.50 before tax. It is one delivery, covers the full quantity, and beats Harlow by 75.70. Harlow is the closest alternative if Trade Depot cannot confirm stock.

Confirm before ordering

Price validity: none of the three quotes gave an expiry date, so ask Trade Depot how long its prices hold
Stock and Friday delivery with Trade Depot
That the 5% account discount applies to every line
That the hinge quantity is 4 pairs
That the batten spec matches what the job needs
Tax: confirm the rate and how it is added locally

What it does

Takes the prices you have from two or more suppliers for the parts and materials on a job or stock order, and shows who is cheapest for each line and for the whole order. It counts delivery, minimum orders, pickup time and returns, not just the unit price.

Use it when: Use when a building maintenance company needs to compare supplier prices for common parts and materials, such as "compare these quotes," "who is cheapest for this order," "which supplier should I buy from," or "check these prices for the job."
