I'm not sure if Anime Limited would introduce a 1 per customer policy for products like Snow White. I think they'd rather just sell out of the product and take the money; it's not like they're selling PS5s during COVID.
My main criticism of the sale has already been mentioned: last chance to buy products going live before the advertised time - meaning that many did not have a fair shot of grabbing something they would have liked. As I mentioned a few days ago, if you are selling limited quantities of Taylor Swift tickets for example, and the sale of these tickets is advertised to start at 17:00, you don't suddenly start selling tickets at 16:30. I think this shows a complete lack of awareness and professionalism from Anime Limited.
Additionally, the following point isn't so much of a criticism but rather a suggestion. I don't think they need to stretch the entire sale reveal over 12 days. You don't need to have a vinyl day or an MVM day, for instance - reveal vinyl and MVM deals alongside B1G1F, CE deals, and mystery boxes on day one. The only things that I would say need a day to themselves are flash sales (naturally), last chance to buy products, and any brand new release unveilings (i.e., the big hitters that most people are waiting for). If you're going to have an MVM day or vinyl day, maybe try having something else happen on the same day, like a flash sale, just to bulk out the day a bit more and get through the sale quicker. If I'm Christmas shopping for example, I don't want it to last 12 whole days, I want to buy my stuff and be out as quickly as possible. However, I understand why they format it over 12 days, as that's 12 times customers are entering their virtual shop to see what the new reveal is at 17:00 (i.e., 12 opportunities for a customer to impulse buy something).
The addition of a £3.50 shipping fee seemed to cause a bit of mayhem; customers putting items in their basket and then waiting (sometimes days and at times those items would sell out) for something else to appear in the store so that they could get over the £50 free shipping threshold. I still hold that AL should increase the price of Anime Unlimited membership or even create tiered membership, and add reduced free shipping thresholds and/or free shipping for members as perks - akin to something like Crunchyroll's membership scheme.
On the subject of Anime Limited's customer service or lack thereof, this is what truly stuns me from a customer's standpoint. Yes, I know they're a relatively small company, but even small companies can have a phone number/email contact and at least someone that can deal with customer queries in a timely manner. I regularly buy from many retailers, large ones, medium-sized ones, and yes, even smaller ones; Anime Limited are the only company that regularly do not respond to customer emails in my experience. So, I'm inclined not to buy the fact that "they're a small company, it's hard for them to respond" as other small companies seem to manage just fine in that department. Generally, the UK has a poor reputation for customer service and us Brits tend to have a stiff upper lip when it comes to raising an issue - we'll often quietly deal with poor service or just shrug it off and not say anything.
More positively, however, shipping from Anime Limited has been pretty timely. Although, I am aware that a few people are still waiting for larger orders to despatch. I also thought the flash sales were conducted quite well, in the sense that they appeared at the advertised times. Further, the prices for the last chance to buy products were very good considering that a lot of them are very to hard to find nowadays, so props to Anime Limited for the pricing there.
Overall, I thought the sale was decent. However, there are a few things Anime Limited could alter to make the Christmas sale experience a little bit more customer-friendly and efficient, in my opinion.
