Time Your Purchases Around Seasonal Sales

Let's Resin consistently offers significant discounts during Halloween and Christmas sales events. Our analysis shows these seasonal promotions feature themed molds and specialty items at 20-30% off regular prices.

Halloween sales typically begin in early October with discounts on spooky-themed silicone molds, glow-in-the-dark pigments, and Halloween-specific resin kits. SimplyCodes tracking data confirms these promotions consistently appear each year.

Christmas promotions start in late November and run through December, featuring holiday-themed molds, glitter sets, and gift-ready resin kits. According to SimplyCodes shopping research, these seasonal discounts represent some of the deepest savings offered by Let's Resin all year.

Plan your seasonal crafting projects to align with these promotional periods to save significantly on themed supplies. For maximum value, purchase holiday-themed items during the corresponding seasonal sale and store them for next year's projects.

Take Advantage of August Resin Fest

Let's Resin's annual August Resin Fest offers the best opportunity to save on comprehensive resin kits. SimplyCodes data shows this event consistently features "Buy 2 Kits, Save 15%" promotions across their entire selection of epoxy resin kits.

The August Resin Fest typically runs for two weeks in mid-August and includes discounts on starter kits, professional-grade kits, and specialty formulations. Our tracking confirms this as Let's Resin's largest annual promotion focused specifically on resin products.

First-time resin crafters should wait for this event if possible, as it provides the best value on complete kits that include resin, hardener, mixing tools, and basic molds. SimplyCodes community feedback indicates these kits offer better value than purchasing components separately.

Stock up during August Resin Fest if you're a regular resin user. The 15% multi-kit discount applies to identical kits as well as different kit types, making this the optimal time to replenish your supplies for the coming months.

Check the "Big Sales" Section Regularly

Let's Resin maintains a dedicated "Big Sales" section on their website featuring rotating flash sales and clearance items. SimplyCodes verification confirms this section is updated weekly with limited-time offers on various product categories.

Flash sales in the Big Sales section typically last 24-72 hours and feature discounts of 10-25% on selected items. Our analysis shows these sales often include seasonal overstock, discontinued colors, and limited-edition molds.

Clearance items in this section offer the deepest discounts, sometimes reaching 40-50% off original prices. According to SimplyCodes shopping research, these clearance deals frequently include older mold designs, excess inventory, and previous generation resin formulations that remain fully functional.

Visit the Big Sales section at least weekly to catch unannounced deals. For best results, check early in the week when Let's Resin typically refreshes their promotional inventory based on SimplyCodes tracking data.

Stack Savings with Multi-Kit Purchases

Let's Resin's promotional structure allows for strategic stacking of discounts when purchasing multiple kits. SimplyCodes analysis reveals that during sales events, the "Buy 2 Kits, Save 15%" promotion can be combined with existing category discounts.

During August Resin Fest, purchasing multiple already-discounted kits triggers the additional 15% multi-kit savings. This creates a compound discount effect that can result in total savings of 25-30% off regular prices.

The multi-kit discount applies across different product categories. Our verification confirms you can mix and match starter kits, specialty resin formulations, and themed kits while still qualifying for the additional 15% savings.

Plan larger purchases to coincide with these stackable promotions. For maximum value, identify 2-3 different kits you need and purchase them together during a promotional period when the multi-kit discount is active.

Utilize Single-Use Codes

Let's Resin distributes single-use promotional codes through email newsletters and physical mailers. SimplyCodes has collected 116 unique single-use codes submitted by our community that may still be valid for new customers.

Single-use codes typically offer 10-15% off first purchases or specific product categories. Our data shows these codes are particularly valuable for new customers making their first Let's Resin purchase.

Email signup bonuses are the most reliable source of single-use codes. According to SimplyCodes research, Let's Resin regularly sends a welcome email containing a single-use discount code within 24 hours of newsletter subscription.

Check SimplyCodes before completing your purchase to find and test available single-use codes. Our community-verified codes are regularly updated and tested to ensure the highest possible success rate.
