Yeah, overseas shipping. I've burned myself more than once by underestimating the cost.
Shipping prices in general has been a big learning curve for me. I ALWAYS used to underestimate. I just couldn't believe how much shipping cost. Now I know: it's expensive!
Also learning that you don't have to wait in line at the post office. I use USPS online and after initially being overwhelmed by all the steps, it's now a breeze and I love just walking past the line to drop my packages off. LOVE!
Oh, and photographs. I've learned what good natural light is and how to avoid getting shadows (for the most part!)
btw, I'm a "thread killer" so this might signify the end of this thread. Sorry, I don't mean to, it just happens. :(:(
