It's hard for me to say if the economy has really caused us any trouble. A few months back we stopped using the credit card processor we had used for a few years and because of that couldn't sell our software. Since we couldn't sell it we've been trying to find a better processor, without much luck.
We own our own business, but we are more computer based, than expecting people to walk in, and we have found that even though the economy is in the toilet, there are still people buying things online.
We have ebay
-ed quite a few things that cost us a bit of money last year that were just laying around collecting dust. My fiance owns his own store we have rent for that (plus ultities). Thankfully we live with his FIL so we don't pay rent for that. (we just split the bills).
Also, we bought a 3rd horse (a birthday present) in september, so that has added onto the horse bill. I did at one point put my mare up for sale, but we have decided to keep her and maybe lease her out come spring time. Time will tell though.
All in all, yes its tough, yes it stressful, but we will go live on the streets before we sell a horse. We made the commitment and buy accepting them we have to take on the responsibility of them for the rest of their lives.
