Question

I want explanation of the second stanza in the poem barter by sara teasdale

Answer 1

The first two stanzas list a great many lovely things that life has to offer, and the first line of both is that "Life has loveliness to sell."  The implication, obviously, is that there is a price for these things, but in the final stanza, the speaker says that we should "Spend all [we] have for loveliness, / Buy it and never count the cost."  In other words, these moments are worth giving up whatever else we have, and we shouldn't hold back anything when we have the chance to purchase the loveliness that life has to "sell" us.  So, yes, we will have to barter, but the speaker says that what we get is of far greater value than anything we must trade for it.
