Any sale item that is purchased can be returned for store credit but not for a refund of the purchase price. Every home appliance and every piece of gardening equipment is on sale along with selected construction tools.

Summary
Every sale item purchased can be returned for store credit, but not returned for a refund. Every home appliance and every piece of gardening equipment is on sale. Some construction tools are on sale.

Notable Valid Inferences
Every home appliance can be returned for store credit
No home appliance can be returned for a refund
Every piece of gardening equipment can be returned for store credit
No piece of gardening equipment can be returned for a refund
Some construction tools can be returned for store credit
Some construction tools cannot be returned for a refund

A
Any item that is not a home appliance or a piece of gardening equipment is returnable for a refund.
Could be false. This answer is a mistaken negation. The correct contrapositive would state that any item returnable for a refund is not a home appliance or a piece of gardening equipment.
B
Any item that is not on sale cannot be returned for store credit.
Could be false. The stimulus is limited to sale items. Items that are not on sale are outside of the scope of our conditions. It could be that some items that are not on sale cannot be returned for store credit.
C
Some construction tools are not returnable for store credit.
Could be false. We know from our conditions that some construction tools can be returned for store credit, but this does not imply that there are some tools that cannot be returned for store credit. The quantifier “some” has the possibility of meaning “all.”
D
No piece of gardening equipment is returnable for a refund.
Must be true. As shown below, we can chain our conditional claims and see that any piece of gardening equipment cannot be returned for a refund.
E
None of the things that are returnable for a refund are construction tools.
Could be false. We know from our conditions that some construction tools are not returnable for a refund, but this does not imply that nothing returnable for a refund is a construction tool. We cannot take the contrapositive of a “some” statement.
