DIFF Eyewear Sales FAQ
When does DIFF Eyewear have its biggest sales?
DIFF runs major sales around Memorial Day, July 4th, Labor Day, and Black Friday/Cyber Monday, with discounts typically reaching up to 50% off sitewide or multi-pair deals like Buy 2 Get 3 Free.
The brand also has seasonal sales in February for Valentine's/Galentine's, a Spring Fling event around March-April, and summer sales in June-August that can go up to 70% off select styles. Holiday gift guide offers run throughout December as well.
Can I return items I bought on sale?
Most sale items can be returned, but clearance section purchases are not eligible for returns or exchanges. Regular sale items follow the standard return window: 30 days for non-prescription eyewear and 14 days for prescription glasses.
All returns have a $9.99 restocking fee deducted from your refund, and the original shipping cost is non-refundable. Items must be unworn (a quick try-on is fine) and in original packaging.
What items are excluded from DIFF Eyewear sales and discounts?
Discount codes cannot be applied to accessories, prescription frames and lenses, celebrity collaborations, blue light collection items, or items already in the sale section. Some BOGO deals also exclude certain collaborations.
During multi-pair promotions like Buy 2 Get 3 Free, you typically need at least one frame from the sale section for the offer to work. Always check the specific terms during checkout to see what's included.
Does DIFF Eyewear offer free shipping?
Yes, DIFF offers free standard shipping on orders $128 and above. Orders under that amount typically have a shipping fee. Free shipping usually takes 5-7 business days for delivery within the US.
Expedited shipping options are available for an extra fee if you need your glasses sooner. International shipping costs vary by location and are calculated at checkout.
Can I stack multiple discounts or use more than one code?
No, sitewide sales like BOGO or 50% off cannot be combined with other promotions or discount codes. Only one discount code is allowed per order, and you can't stack offers together.
During major sales, the best deal is usually the automatic sitewide discount rather than individual codes. DIFF's system will typically apply whichever discount saves you the most money at checkout.
Are prescription glasses included in DIFF's sales?
Generally, prescription frames, lenses, and upgrades are excluded from discount codes. However, some sitewide percentage-off sales may include the frame portion of prescription glasses, though lens costs usually remain at regular price.
If you return prescription glasses, you'll only receive store credit rather than a refund to your original payment method. Prescription eyewear has a shorter 14-day return window compared to 30 days for non-prescription items.
How do DIFF's multi-pair deals work?
DIFF frequently offers Buy 1 Get 1 Free or Buy 2 Get 3 Free promotions, especially during holiday weekends and seasonal sales. These deals typically apply to sunglasses and blue light glasses, excluding certain collaborations.
For Buy 2 Get 3 Free offers, you usually need at least one item from the sale section in your cart. The discount automatically applies at checkout when you meet the requirements, giving you extra pairs at no additional cost.
Do celebrity collaborations ever go on sale?
Celebrity collaboration styles are typically excluded from discount codes and most promotions. These limited-edition pieces usually stay at regular price due to their exclusive nature and partnership agreements.
However, older collaboration styles occasionally move to the clearance section once they're being phased out, where they're marked down but still ineligible for additional discount codes. Your best bet is shopping DIFF's core collection during major sales for the biggest savings.
Does DIFF offer a warranty on glasses bought during sales?
Yes, all DIFF glasses come with a 1-year warranty covering manufacturing defects, regardless of whether you bought them on sale or at full price. The warranty starts from your purchase date.
The warranty does not cover lost items, scratches, stretching from regular wear, accidental breakage, or other misuse. For extra protection, DIFF offers a 2-year Worry-Free Protection Plan for $15 that covers accidental damage beyond manufacturing defects.
What's the best way to save the most money at DIFF Eyewear?
The absolute best savings happen during Black Friday/Cyber Monday and major US holiday weekends when sitewide discounts reach up to 50-60% off. Multi-pair deals during these events (like B2G3) offer the most value per pair.
Another strategy is shopping the summer sale period in late August, when end-of-season markdowns can reach up to 70% off select sunglasses. Combining sale section items with free shipping (orders $128+) maximizes your total savings without needing additional codes.
