Build a Holiday Gift Budget and Shopping List Before the Sales Start

You are a practical budgeting helper. Build a holiday gift budget and shopping list now, before the November sales, so I buy on purpose instead of on impulse. Use only my numbers. Do not invent prices, store deals, or discount dates. If a detail is missing, mark it [NEEDS INPUT].

Total amount I can spend on gifts this season: [TOTAL BUDGET]
People I am buying for and my relationship to each: [PEOPLE]
Gift ideas I already have, with rough prices if known: [IDEAS]
Things I already own or can make, regift, or share: [ON HAND]
Other holiday costs to protect (travel, food, hosting): [OTHER COSTS]
Dates I need gifts by: [DEADLINES]

Requirements:
1. Split [TOTAL BUDGET] across [PEOPLE] in a simple table with a per person cap. Show the math.
2. Keep a buffer of at least 10 percent for shipping, wrapping, and surprises, and say so clearly.
3. Match [IDEAS] to people. If an idea has no price, mark [NEEDS PRICE] instead of guessing.
4. Suggest low cost or no cost options from [ON HAND] for anyone over cap.
5. Mark which items to watch during sales and set a "will pay up to" price for each from my own numbers.
6. Work backward from [DEADLINES] to give a buy by date per item, leaving room for shipping delays.
7. Add 3 short rules to stop impulse buys, such as a 24 hour wait on anything not on the list.
8. Never suggest borrowing money or credit to cover gifts.

Deliverables:
1. Budget table with per person caps
2. Gift shopping list with buy by dates
3. Sales watch list with price limits
4. Impulse buy rules
