This is an awesome bluetooth speaker, I got it with the TGG $20 discount a while back and it has treated me well so far. After the discount it comes out at $25 for the unit, so it's a killer price.
Here is the link for the ethernet cord.
You can substitute the extra $5 needed with anything from the good guys but this seemed to be the most logical and cheapest option. Here is a link that will list from cheapest to most expensive in the computing category.
You can actually add any product to supplement the remaining $5 providing it has free shipping and is exactly $5 for this price.
Enjoy :)
Normally you can order anything off eBay to make up the extra "$5". Up to 10 items per transaction. Although it may not apply this time?
