I've been making a bit of money during the holidays from retail arbitrage for the past few years. This year, I realized that it has gotten really crowded out there and isn't worth the effort anymore. I noticed that prices adjust on Ebay much more quickly after retailers post deals. Total profit this holiday season has been $100 only. Below is a list of things I've bought for reselling.

1. Cameras from Bestbuy. Purchased 2 @ $799 each. Ebay sold prices before were $1500. As soon as I received the items, prices dropped to $900. I returned the items to Bestbuy.

2. Diesel watches. 20 @ 125 each. Ebay sales indicated that they would sell for around $265 each. Prices dropped to $150 by the time I was ready to ship.

3. Also tried my luck with 3 PS4s @ 399 each. Sold 1 for a profit of $100 and the rest were returned.

Lucky for me, all purchases came with either free return shipping or free store returns. However, after accounting for the time spent researching all of this, I don't think I came out ahead. I won't be trying this out again unless I can find deals on products that are highly liquid with stable prices. This space has gotten way too crowded.
