📌 PLEASE READ BEFORE PURCHASING

How I source items:

Most of my inventory is sourced from flea markets, thrift stores, estate clean-outs, and donation lots. Because of this, many items are incomplete and may be missing accessories, cords, chargers, mounts, adapters, manuals, or proprietary connections.

Important rule of thumb:

👉 If it is NOT shown in the photos, you will NOT receive it.

👉 If it IS shown in the photos, you WILL receive it.

Photos are considered part of the description.

⚠️ ABOUT CONDITION & COMPATIBILITY

I do my best to test items when possible. All items are sold as working unless clearly stated otherwise or listed under “For Parts or Repair.”

That said, there may be blind spots or niche compatibility requirements I’m unaware of (specific cables, software, mounts, power supplies, etc.). Please do not assume anything is included unless it’s shown. If you are unsure whether something will work for your specific setup, ask before purchasing.

❓ QUESTIONS & COMMUNICATION (IMPORTANT)

I receive a high volume of messages and may not always respond instantly. If you have a question that could be a deal-breaker:

✔️ You may purchase the item first, then immediately message me with your question.

✔️ I will prioritize answering questions on recently purchased items because I want to avoid returns.

✔️ If my answer changes your mind, you can request a cancel before shipping — no hassle, no problem, full refund.

My goal is zero surprises for both of us.

📦 BUNDLING & DISCOUNTS (HIGHLY RECOMMENDED)

I strongly encourage bundling and I’m much more flexible on price when items are bundled.

How to bundle items:

1. Add multiple items from my store to your cart

2. Go to your cart

3. Select “Request total” or “Send offer”

4. Send a bundled offer — I’ll review it

Bundling saves on shipping and usually gets you a better overall deal.
