Hi,
Sorry for a late reply.
1. Label for the sale price – I could add some option for that in “Hide regular price for products on sale” section, but I think you can already do it with the existing plugin by selecting “Instead of the standard price” as “Position” and then using %price%
placeholder in “Final Template” options, e.g.:
Our price: %price%<div class="price"><label for="alg_wc_msrp">MSRP</label>: <span id="alg_wc_msrp"><del>%msrp%</del>%you_save%</span></div>
2. MSRP strike-through – actually it should be stricken through – please make sure that you have <del>
tag in your “Final Template” in “Archives Display Options” section (i.e. for shop / category pages), i.e. this part:
... <del>%msrp%</del> ...
Please let me know if you have any questions.
