Pretty good deal on a 2 pack (5 or 10 packs are fall less). PETG really dropped in price but seems to be stabilizing at an everyday price of $10/spool or $18 for two. This combo was $20 a few months ago. Couple dollars cheaper then the every day price.

Relatively new to the 3d printing space. I have been getting my filament from Microcenter, and everything has printed nicely. Should I be concerned about some of these ridiculously cheap Amazon deals? Is there a difference in the quality of the prints when using cheap filament?

I've only bought two PLA packs so far from Amazon (Elegoo and AnyCubic) and they were cheaper than MicroCenter at $10/kg and they were fine

Does not need an adapter. Will work fine with the AMS 2 Pro.

Would you mind giving an opinion why you didn't pick sunlu as one of the PLAs? I thought it's a good brand and seems popular but hoping to get some insights about it. TIA

I meant that the ones I bought so far were cheaper than the ones at micro center even though they are reputable brands afaik. I've only bought two packs of filament because I just bought the printer, I didn't mean these were the only two brands I buy.

I read exactly the same thing you've mentioned and was planning to buy sunlu eventually but I'm aiming at $10/kg or less, that's why I haven't bought anything else yet.

honestly, I have tried filament from a ton of different brands including cheap ones, I cant tell a difference if its printed with bambu pla or "cheap" pla.

I am in the same boat and IMHO the answer is to make sure you have an easy way to return bad products. I've purchased several spools from Amazon and the Aliexpress deals regularly posted and it has been hit or miss on printability for spools within the same order from both. I'm drying them all out before using them but some spools work great and others don't. I had my first clogged nozzle this week from an Ali order and it has been a PITA to deal with. I think I'm going to stick with Amazon and other more return-friendly suppliers. I've not done a lot of purchases in general with Ali but it is Amazon 3rd party marketplace on steroids and I don't think I'm a fan.

I had a really bad experience with a lot of Sunlu filament from Amazon. That said, I understand Kingroon is rebadged Sunlu and that has also been hit or miss for me.

Were commenting on PETG, not PLA.

From this side of the peanut gallery, I'd say the prices on Amazon are normal (not "ridiculously cheap")... but rather the Microcenter prices are unnecessarily inflated.
