LeetCode is the best platform to help people practice solving coding problems and prepare for technical interviews. The main users are software engineers. LeetCode has over 1,900 questions covering many different programming concepts.
I’ve been using RetailMeNot on and off for a while, and overall it’s a helpful site if you like hunting for discounts before checking out online. It’s super easy to use, and I like that you can quickly search a store and see available promo codes or cashback offers without much effort.
That said, it’s a bit hit or miss. Some codes work perfectly and save you a decent amount, while others are expired or have restrictions that aren’t obvious until checkout. When it works, it’s great. When it doesn’t, it can feel like a waste of time trying multiple codes.
I also appreciate the cashback feature, but it’s not always as competitive as other cashback apps, and it can take a while to track. Still, for a quick check before you buy something, it’s worth using.
RetailMeNot provides a wide range of deals throughout the year from Grocery to clothing. I've got some amazing offers through using this site over the past three years.

General Coding Assessment (GCA): the harder of the two, but manageable with preparation. It's done on CodeSignal, either in person or online. To prepare, practice DSA questions on competitive programming sites like LeetCode, Codewars, and CodeChef for 1–2 weeks, and you should be in good shape. - Source: dev.to / 29 days ago

Plain BST. Fine when input is random or the problem doesn't require worst-case guarantees. Tree problems on LeetCode typically assume balanced input and don't ask you to maintain balance yourself. - Source: dev.to / 4 months ago
Your preparation should not be random. Platforms like LeetCode, Codeforces, and GeeksforGeeks are tools—but what matters is how you use them. - Source: dev.to / 4 months ago

You could also try retailmenot.com and see if anybody has listed newer codes. Very spotty luck with that site tho. Hey, even if it saves $20, it's worth the time! Source: over 3 years ago
If you should decide to try Catherine's again, try doing a google search for Catherines Free Shipping or something like that. I often find a free shipping code on retailmenot.com Same with a lot of other stores. I've happened on coupons and ended up with unexpected discounts. There are a few coupon sites out there.

You can also get 8% cash back from retailmenot.com. That would basically subsidize the cost of upgrading the ram to 32gb dual rank. Source: about 4 years ago
Protect yourself by first pulling your FICO score (go to MyFico and pull your own score, and you can get a coupon from retailmenot.com) and shop around. You can shop around for rates without a hard pull so you know how much car you can afford for the interest rate you would qualify for with that FICO. When you pull your own FICO this way, it doesn't count as a hard pull and puts more knowledge in your hands. Source: about 4 years ago
I'm in Canada, too. Lands' End has fast shipping to Canada, and I've bought a lot of quality basics from them. They have lined leggings here, though I haven't bought them myself: https://www.landsend.com/products/womens-high-rise-serious-sweats-fleece-lined-pocket-leggings/id_359400?attributes=3298,44967. Lands' End always has discount codes (sign up for emails or check retailmenot.com), so never pay full price. Source: over 4 years ago
