OR....OR.... just hear me out:

​

Live in a country with proper consumer protection, where if something breaks within the legally defined warranty period. they have to repair it/send you a replacement part. [and warranty laws do not look at the type of "commercial" sale, if you buy it in a store, even if its discounted by 99.999% and it breaks 1 week later, they have to give repair it/give you a replacement unit]
