All this for the low price of I want to list several features of a product and then at the end I want to finish with:

all this just for the minimum price or all this for the minimum price

My best attempt was 获得这一切只需要最低的价格.

Which is kind of similar to something like:

all this for just $29.99

or

all this for only $29.99

or equally

all this just for the minimum price of $29.99

I use the term 'minimum price' in my sentence because it makes sense in it's context.

I'd be interested in the Chinese version of the first sentence most importantly, but versions of all the others would be interesting as well.

I guess the title for this could also be all this for just/just for..

EDIT: If all this just for the minimum price seems weird then simply add the price on the end all this just for the minimum price of $2.99.
获得这一切只需要最低的价格 sounds very unnatural. you can simply say 只要$29.99 or 只需$29.99) which contains the meaning of minimum price without mentioning it. To be clear about "all this", I think you can use 以上(all above) or 以下 (all below) or 全部(all)

If your Chinese version referring to Chinese currency, the dollar sign is ¥.
