1. Google webmaster has a "Cover - redirect error" error on the following pages:
bonparik. ru/catalog/?bp_brand[revlon]=revlon&arrfilter_p1_max=47850&arrfilter_p1_min=280&set_filter&PAGEN_1=3

This error needs to be corrected.

2. Our site is associated with 1c, colors that are available in salons are displayed in the block bonparik. ru/catalog/?fast_delivery=y
Previously, the site had synchronization, a separate button, when clicking the products on the site synchronized with 1c and the models that are available is not displayed. Conversely, if the product appeared - then appeared in the block fast delivery in the right shades. Now we are carrying out this work by hand. To do this, the product card has a window "There are goods available." Is it possible to automate this process?

3.Many goods go to the basket without a discount. We have two prices - ordinary and honey. Indications. The basket does not always show a discount and wigs come out with a full price. All goods should come out at a discount. An example is bonparik. ru/catalog/iskusstvennye/kaylee/. And one day can go out normally at a discount, another day without.

In the applications specify the cost and timing of work on each job. If you cant do everything, tell me what tasks you can do
