This may be an off topic in other forum sections, so I will try here

I am about to buy some some keycaps on taobao.com via obook. I know it is a recommended shopping agent here. I also found 2 other agents, taobaofucus.com and taobaoenglish.com. The charge a lower commision and have more functional web sites

. I am wondering if anyone here has experience with these two other agents before.
Thanks.
