As pete states, HALO is doing good
Since the website relaunch, followed by the release of the Triton Tank system, HALO has been getting a lot of press, and all of it has been positive press, which leads to higher demand for the products. Halo just didn't realize to what extent the positive buzz was going to create, and so supply dwindled a bit.
One might imagine a company having a warehouse full of merchandise waiting for customers to buy it. But in reality, most company do have a budget to follow, and might have sided with the conservative in these hard-pressed economic times. But it's evening out, and Cinder Ella mentioned that merchandise is on it's way back.
Overall, it's good to see Halo doing well with their investments. It can be frustrating for the customer coming to the site and finding those wanted items out of stock. Halo, as a company, now knows it's level and the has a better idea of selling trends, so after these growing pains will be better equipped to keep items in stock.
