Here is the rewritten purchase and subscription terms policy, precisely updated to match the actual operational structure, pricing models, subscriber perks, and coupon guidelines for the store.

Purchase Options & Terms of Service

At EnviroBiotics, we offer flexible ways to purchase our environmental purification systems and maintain your home’s probiotic ecosystem. Below are the terms governing One-Time Purchases, our Subscribe & Save program, and Coupon usage.

1. One-Time Purchases (Full Price Options)

When you select a One-Time Purchase for any EnviroBiotics hardware system or replacement cartridge, you are making a single, non-recurring transaction.

• Pricing: Hardware systems and individual refills are billed at full retail price.

• Warranty: All hardware purchased as a one-time transaction includes our standard 1-Year Limited Warranty from the original purchase date.

• Shipping: Standard shipping fees apply at checkout unless your order total meets our current promotional free shipping threshold for continental U.S. orders.

2. Subscribe & Save (Refill Subscriptions)

Enrolling in our Subscribe & Save program is the most convenient and cost-effective way to ensure continuous protection for your indoor environment. By selecting a subscription, you agree to recurring billing and deliveries based on the frequency established for your device's lifecycle.

Subscriber Benefits & Incentives

• Instant Device Discounts: When you purchase an EnviroBiotics device alongside an active refill subscription, you unlock an immediate 10% discount on the hardware system at checkout.

• Exclusive Refill Pricing: Future cartridge deliveries are automatically discounted below full retail cost (e.g., custom pricing structures for BioLogic Mini, Biotica 800-NV, and BA-2080 twin-packs).

• Complimentary Shipping: All recurring subscription refills are shipped via Free Priority Shipping, entirely eliminating surprise delivery fees.

• Lifetime Device Warranty: As long as you maintain an active, uninterrupted cartridge subscription, your companion EnviroBiotics hardware unit is upgraded to a Lifetime Warranty. If the unit experiences manufacturing defects at any point during your subscription, EBT Corp. will repair or replace it at no cost to you.

Billing & Management

• Your payment method will be stored securely and automatically charged every 6 months (or at the designated lifecycle interval for your specific model) prior to fulfillment.

• Complete Flexibility: There are no long-term commitments. You can pause, skip a delivery, adjust your processing dates, or cancel your subscription at any time through your customer account dashboard.

• Warranty Reversion Notice: If you choose to cancel your subscription, your hardware unit's warranty will immediately revert to the standard 1-year term calculated from your original purchase date.

3. Coupon and Discount Code Usage

To maintain fairness and the integrity of our pricing structure, promotional codes and coupons are governed by the following rules:

• Exclusions on Subscriptions: Coupon codes, introductory promotional discounts, and reward point redemptions are applicable only toward One-Time Purchases. They cannot be stacked or applied to Subscribe & Save recurring orders, as subscription items already feature built-in lifetime discounts and shipping incentives.

• Stacking Restrictions: Unless explicitly stated otherwise in a specific marketing campaign, only one promotional discount code can be applied per transaction at checkout.

• Rewards Integration: Points earned through our Ecosystem Rewards program can be converted into custom discount codes for one-time purchases, but cannot be used to offset recurring subscription renewals.
