Xi'an Saige's come in and give a quote, thanks!
The offer and the actual price is not the same. You still come in person, after the price is hard to cut is, never according to the offer to install, then you will lose. Anyway, the general assembly you bring 4000 can be assembled very well, but do not do in one on the office, ask more than a few, give him a list of installed, let them say the offer and then cut the price to find the lowest installed can .
