Price‑Timing Tips

GPU prices drop most often mid‑week and weekends.
If the GPU or motherboard is above the high end of the range, wait 48–72 hours.
Amazon frequently rotates discounts on CPUs and SSDs every 2–4 days.
If the total is above $720, you’re catching a spike — wait for the dip.

Cashback Optimization

Using a card with 3–5% cashback on online purchases effectively lowers your build cost without changing any parts.

“A $700 parts list can return $21–$35 in cashback instantly when using a card with 3–5% back on online purchases. This reduces your effective build cost without sacrificing performance.”
