Webengine Bulk Pricing for WooCommerce

Webengine Bulk Pricing for WooCommerce adds a screen under Products → Bulk Price Editor to update prices on many products at once:

• Regular price: set a fixed price, or increase/decrease by a percentage or a fixed amount.
• Sale price: set a fixed sale price or a percentage discount off the regular price.
• Flash sales: sale price or discount plus start/end dates, interpreted in your site’s timezone.
• Clear sale prices and dates in one click.
• Psychological rounding: nearest cent, whole number, or prices ending in .99 / .95 / .50.
• Variable products: every variation is updated and the parent price range is re-synced automatically.
• Preview before saving: a before/after table shows exactly what will change (and what will be skipped, and why) — nothing is written until you confirm.
• Filter by search (product name or SKU), category, on-sale status; select per page up to 200 products.

The plugin stores no data of its own: it only updates standard WooCommerce product fields, and leaves nothing behind on uninstall.

Safety rails

• A sale price is never saved above the regular price — even after rounding.
• Prices can never go negative.
• Changing a regular price below the current sale price clears the sale price.
• Everything runs under the manage_woocommerce capability with nonce protection.
