Home Depot has a great deal on Raised Garden Beds. You can get them for $89. These have a trellis which is nice especially for small spaces because it allows you to also grow vertically.
I have been looking at raised beds for my children this year and this is the cheapest I have seen so far.
Shipping is free so not having to tote this around the store is a huge bonus for me.
Head over to Home Depot to have a look. There is a limit of (5) per order.
This item cannot be shipped to the following state(s): AK,GU,HI,PR,VI.

It looks like the one above might be sold out now but this raised bed is available for $79.99.
This also has free shipping and the reviews are excellent.
Type in “Greene’s Fence” and you can see several other options that are similar.
Thanks Karen!
These have sold out online, however we were able to fond one of similar dimension without the trellis for $79.97.

Ok thanks for letting me know Karen, I will update the post!
It looks like it was an online special only valid yesterday (3/20/13). 🙁
Ola,
I checked before posting and it was available when I posted. Just refresh your page and you can see some other options that are currently available. Please note I can not guarantee how long they will last.
I recently learned that a veggie garden can grow from a trellis-like apparatus made from an old wooden pallet. I think I saw it on recyclebank. Maybe you can ask Costco or grocery store for an old pallet to upcycle? 🙂
Endcapps – that is a great hint. Just make sure the pallet has not sprayed with chemicals. A lot of pallets are sprayed with a chemical that resists bugs and mice. yuck. I wouldn’t want that touching my veggies.
